Jeremy walked through the dog park on his way home after a long day of work. His black short hair, white t-shirt, and blue shorts kept him cool on that warm day.

While he didn't own a dog, a walk through the park shaved a good ten minutes off his commute. As the sun was setting, there was little action in the park. Jeremy didn't spot very many people, and even fewer dogs. With a small sigh, he walked through the grass, cutting off the main path to shave some more time. He kept his eyes on the grass as he walked. While most people picked up after their dogs, he had found the occasional pile of poo to avoid.



Jeremy paused when he saw something black and shiny. It didn't look like dog waste, it looked different. At first, he thought it was some sort of toy, and curiously, he reached down to give it a poke. "A collar?" He picked it up and gave it a look over. The collar was a third of a foot in height, and it looked big enough to fit around a human. The collar felt like it was leather, and there were silver spikes poking out of it. Jeremy gave the spikes a curious poke, and found out they were rubber. He glanced around for a nametag, but he saw none. He then looked around for any nearby dogs and people, but he also saw none. He figured maybe somebody dropped it, but the collar looked as if it was brand new.



As Jeremy held onto the collar, he swore he heard the sound of a faint dog cry, though it came as an echo, he still looked around to try to find the source of the noise. "Hello?" He glanced around for any sign of a dog, yet he spotted nothing.



He heard the whine again, and this time, he identified where it came from. The sound came from inside his own head, it was an echo of a girlish dog whine, one that sounded as if they were begging for something, something that Jeremy couldn't quite identify. "Odd..." he mumbled. 



He began to walk away, and this time with the collar in hand. He wasn't sure what he was going to do with the collar. He passed by multiple trash cans as he walked along, but he thought it was a waste to throw a dog collar away that was in such good condition, yet at the same time, he couldn't find any dog that was lacking a collar, nor did he see anyone even look as if they were trying to find a collar. By the time he got to the park exit, he figured he'd just take it home with him.



Jeremy walked into his small house with the collar in his grasp. He lived with his fiancee Ashley, but he figured that she must have still been at work as she wasn't there by the time he went through the front door. He walked through the small hallway, and into the living room where he took a seat, and turned on the television. He twirled the leather collar on his index finger, and glanced down at it more than he looked at the television. There was just something about the collar that just felt so bizarre. He could still hear the sound of a dog whine from it, as if the collar itself was calling to him.



Jeremy looked to the left of him, and then to the right of him. With a small smile, he opened up the clasp of the collar, placed it around his neck, and then closed it. The latch was a fairly simple attachment that functioned much like a belt. He put it around his neck, and left enough room to fit his fingers in it. He wasn't entirely sure why he did it outside of the rational of he just wanted to. He felt silly for putting on a dog collar, but at the same time, it just oddly felt so...right. Once Jeremy wore the collar, the sound of the dog whining left his mind, but he instead heard the noise of a dog being...happy. He heard the barks, he imagined the tail wag, and he just smiled at the image as he leaned back, and watched television.



Jeremy's stomach suddenly grumbled with the desire for food. He realized that it was about dinnertime, and he hadn't eaten much of anything. He got up from the living room, went through a small dining room, and right into the kitchen to get something to eat. He opened up cupboard after cupboard. At first, he wanted something cheap and easy to make, but he eventually settled on making himself a hamburger with a patty from the fridge. He set it up on the stove, and started cooking. He was ready to grab salt, pepper, cheese, lettuce, various ingredients that could go on a hamburger, but he hesitated. Something deep down told him that he should just cook the hamburger meat and eat it, not even using a bun. He added a second hamburger patty and cooked that with the first. As the scent of cooking burgers filled the air, Jeremy felt his mouth fill with saliva. It felt as if there was an excessive amount of drool, so much so he couldn't help but open his mouth, stick out his tongue, and let the drool just fall onto the pans, sizzling away as it touched the hot metal.



After a few minutes of cooking, Jeremy turned off the stove, put the burgers on a plate, and walked back out to the living room. He was still drooling, but he closed up his mouth at the very least. He took a seat on the couch, and ate the hamburgers wolfishly. He gobbled down each bite of the meat. Jeremy barely took the time to savor the flavor of the beef. Just that it was food, and it was good. As he continued to devour the meat, his teeth sharpened to make eating easier, and his chewing grew louder, at least to him, as his ears became a furry brown color, and moved up to the top of his head. A furry short tail also sprouted from his rear, and he was completely oblivious to the changes. He let out a loud "Urp" once he finished, patting his stomach happily. "Mph. That was good." He didn't care that his mouth was wet with both the beef juice and his own drool, it was the best hamburger he had ever cooked, even if he ate it without condiments or buns.



Once Jeremy finished his meal, he leaned back against the couch, and watched television. It took him only a moment to detect something wasn't right behind his back though, as he felt what felt like a large stick, and he could hear rapid thumping behind him. It also almost felt as if he were laying back on his own arm, even though his arms were right beside him. He leaned forward, looked behind him, and yelped. He saw a short fluffy dog tail, and when he looked at where it was connected to, he let out another yelp again, one that sounded very much like a canine.



"W-what?! I must be going crazy or something." Yet, even as Jeremy went down to touch the tail, he could feel the fur, the soft flesh underneath, and he could feel the other end too, the tail being grabbed. The tail stopped wagging so rapidly, and while he felt as if he had some control over it, it was incredibly basic control. He could wag it from one side to another, and that was it. He had control of the muscle before the tail, not the actual tail itself.



Jeremy stared at his tail in disbelief. As he was holding it, he couldn't help but feel a strange heat between his legs. "Uhn," he mumbled. Thoughts of dogs, male dogs, mounting him with their canine cocks slowly grew stronger in his mind. He let out a light canine whimper, and then released what had just came out of his mouth. "What's...what's happening to me?" Jeremy got up, and rushed to the bathroom. He could feel the blood in his body also rush between his legs, slowly making him more and more aroused.



Once in the bathroom, Jeremy noticed his canine ears on top of his canine tail. He opened his mouth in panic, and then saw his sharp teeth. He then looked down at his neck at the collar he had just put on. Jeremy reached out to undo the clasp in the back, but as his fingers worked the latch, those very same fingers shrank and fused together, except for his thumb which pulled backwards. His fingernails fell out, but claws were quick to grow in their place. Jeremy couldn't see the changes happening to his hands, but he could feel them, and how much harder it was to undo the collar. He pulled his hands back, and stared at his fingertips, now at less than half the length they once were, slightly wider, and unable to flex nearly as well as they could before. "Crap, crap, crap." Jeremy felt sweat start to pour down his body as panic mode set in. He couldn't rip the collar off with his bare hands now, he could barely even flex his fingers to grab hold of objects. He mentally thought to himself that he needed something, something like a cock in his needy cun- "No!" he shouted to himself. He didn't even have a cunt, but he couldn't deny there was a burning sensation between his legs, and an uncontrollable arousal he could not get under control.



Jeremy couldn't stare at himself in the bathroom any longer. He was worried about the collar, but he wasn't sure how to take it off. Any thoughts he had about ideas to get the collar off were quickly changed into that of dogs, cocks, and puppies. He let out a light whine as he thought about puppies, knowing very well they needed to suckle on their mother's teats for nourishment, but he had no way to provide such things. Just as he had that thought, the front of his body tingled. He could feel his two nipples grow erect, and more sensitive sensations beneath his nipples. He raised his shirt, and his eyes widened at the sight of six additional pink spots, directly down his first pair of nipples, giving him eight in total. "W-what...what...?" he stammered in disbelief. He took off his shirt, and tossed it to the ground. He already knew he had so much canine apart of him, now he saw the nipples too, but they didn't look like dog nipples, the nipples that slowly grew from the pink spots on the front of his body looked far too human. Jeremy ran both of his index fingers down each row of nipples, and shivered at the pleasurable sensation of each nipple. 



Jeremy felt his shaft suddenly burst cum from between his legs, though it was only one pulse, it still felt incredibly powerful, as if that one pulse was more than he had ever came before. It was hard to even stand up straight as his legs quivered with his short, but intense, orgasm.

Once finished, Jeremy reached down between his legs to give his crotch a grasp. He could tell something was wrong, and when he lowered his pants and underwear to see, sure enough his cock and balls had shrunk down more than half in size. The shaft was barely three inches, while the balls were almost the size of two peanuts. "T-this thing is going to make me a dog, isn't it?" he said to himself with panic. "A-a girl dog, a bitch..."



Jeremy knew he had to get the collar off, but he wasn't sure how he could even do it at that point. His hands were changed into paws, so grabbing anything with his fingers was out of the question. He rushed into the kitchen, leaving his pants and underwear behind, and glanced at the kitchen drawer. He pulled open the drawer with his paws, and tried to grab onto a knife anyways, although the butter knife kept slipping from his paws. "I just need...I need a master. Someone to take care of me..." he let out a light whimper.



Jeremy tried to clear his mind and focus on thinking about getting some help. "N-no, I don't need a master. I need...Ashley!" He was well aware that Ashley wasn't going to be home for quite some time, but he thought if he could call her, maybe he could convince her to come home early. He rushed to a small table near the couch in the living room where a cordless phone sat. Jeremy knocked the phone onto the ground, and tried pressing the buttons. Unfortunately for Jeremy, his fingers were nothing more than fat stubs. Each one looked like a swollen thumb twice the normal size, unable to bend, and complete with black paw pads for walking. Jeremy just couldn't press a single button on the phone efficiently enough to dial up any numbers. Jeremy whined lightly, much like a dog would, with frustration. "She only works a few miles away...maybe...maybe I can just drive there instead." He told himself. He rushed to the door, but mid run, he fell over with an 'oomph' onto the hardwood floor in the living room.



Jeremy tried to stand back up, but it felt difficult to do so, as if his front weighed him down. He could feel his eight nipples start to pull downward with him, and with him being topless, he was able to look down and see that he was developing boobs. Each nipple developed a small sphere behind it, slowly pushing out until they reached an A cup. The size was modest, but it was the fact that Jeremy had four pairs of tits in total running down his torso that was even more frightening.



Jeremy quickly gave up trying to stand back on two legs, and just made his way to the door. His legs hadn't shrunk, leaving him with his ass high in the air, thankfully still covered by his pants. He made it to the door, and he leaned up to the round brass doorknob. He pressed his paws around the knob, and he tried to turn it, but with no luck. His paws just didn't have the dexterity needed in order to work a doorknob properly.



After some time trying to open up the door, Jeremy let out another light whine. He squatted down in front of the door, much like a dog might sit. He then reached up, and scratched the door with his new paws. He didn't even notice the new small black tips that had taken place of his fingernails, making light scratches on the wooden door. As he scratched, he whined like a needy dog. "Ashley!" he cried out. He was at a loss about what he should do, he needed someone, anyone, to help him, yet he was alone.



Jeremy's new canine ears suddenly picked up the sound of a car door slam He couldn't quite tell who it was, even though his nose had become more sensitive, the door was still in the way. He could hear footsteps approach the door though, and his tail wagged rapidly and happily. He sat on his haunches, his erect shaft rubbed against the floor through his pants below him. It has to be Ashley. It just has to! He thought to himself. He wasn't sure how Ashley was going to react to him being so...transformed, but he just had to get someone to help him remove that collar before things got worse.



The door opened to reveal a woman on the other side. The woman had a build like Jeremy used to have, except wider hips and a large breast. She had blue and pink dyed hair that went down to her shoulders, white skin, and she wore a waitress uniform. It was Ashley, and she had just came home from work. Upon seeing Jeremy, she jumped in shock. "When did Jeremy get a dog?!"



Jeremy opened his mouth to speak. He wanted to shout to Ashley that he wasn't a dog, he didn't even look completely like a dog, yet when he tried to speak, only barks came out of his mouth. I can't speak?! He mentally asked himself. He tried talking again, yet nothing but barks and whines left his maw.



Ashley grimaced at Jeremy. "So noisy too. Quiet!" Ashley shouted, as if she were trying to give a dog an order. She snapped her fingers, and pointed a single finger down at him.



Jeremy's mouth was open, but it quickly slammed shut once Ashley gave the order. He wasn't sure why he obeyed so quickly. His heart thumped wildly as his mind was filled with fear. He couldn't imagine how Ashley saw him as a dog. He still had human skin, sure he had some fur, and eight tits, paws, and a tail, but he still looked human enough to be recognizable, at least that's what he thought when he looked down at himself. He looked to him, and then back to Ashley with wide eyes.



"Good girl." Ashley let out a frustrated sigh. She closed the door behind her, and then she began to look around the house. "Where is that man? He bought a dog, he couldn't just leave her, could he?!"



Jeremy wanted to let out a whine, but he was ordered to be quiet. She called me a girl?! He thought to himself. It was true that his cock felt strange as it dangled between his legs, it felt much smaller than he remembered, and he couldn't see it beyond his slowly growing boobs though to tell what exactly it looked like.



Unable to find Jeremy, Ashley just let out a huff. She looked ready to take a seat on the couch, but then she looked down at Jeremy with a grimace. "Who knows how long you've been here...I bet you're hungry, or maybe you need to go use the bathroom."



Jeremy hadn't even focused on his hunger or his bathroom needs. He had eaten fairly recently, he remembered that much, but he didn't remember ever using the bathroom. He shook his head left and right wildly, trying to tell her wordlessly that he didn't need any of that.



Ashley didn't seem to notice Jeremy shake his head, or she didn't know what it meant. "At least he was kind enough to get you a collar and leash first." She said as she walked over to the table in front of the couch. She grabbed a pink collar and pink leash, and then walked up to Jeremy to wrap the collar around his neck.



Wait. Where did THAT come from?! Jeremy mentally asked himself. His eyes widened as he watched Ashley take hold of the collar and leash. He immediately backed up to the wall behind him, and he felt his tail brush up against the wall. He kept moving back until he felt his balls press up against the wall, and let out a small yelp as it felt as if pushing his balls up against the wall suddenly just made him need to use the bathroom badly in a way he couldn't explain it.



"Stay." Ashley commanded, and then she put the leather pink collar around Jeremy's neck. "He even named you...slut puppy?" Ashley raised a brow as she looked at the tag around the collar. "Why would you even NAME her that?" She let out a frustrated sigh. "Whatever, you can't have a leash without a collar, and the collar nametag isn't coming off."



Jeremy was ready to bolt the minute the collar came close to him, but when Ashley commanded him to stay, he felt his four legs stiffen in place. He just couldn't move, he couldn't struggle, he was forced to stay there and watch humiliatingly as the collar was wrapped around his neck like the dog he was becoming. He whined as he felt more of his backside change, not just his cock and balls, but he couldn't see exactly what was happening. He felt his anus become more pronounced than it should have as it was visible to the world. His tailhole grew, doubling, tripling in size behind him. He couldn't see directly behind him, though he could feel his sensitive pucker stick outwards, growing almost past his own ass cheeks.



"Now, heel." Ashley pulled the leash. "Go. Let's go outside." She pulled the leash for Jeremy to follow, and opened up the door. "Hopefully it's just number one, or I swear I'm calling the man's cell phone and demand he comes...wherever the heck he is now, and tell him to pick up your poop."



Jeremy couldn't help himself. Whenever Ashley ordered him to do something, he felt compelled to obey. He walked up to Ashley's side, and let out a tiny whimper. He could feel his canine ears tilt back. He wished he had a mirror to see how different he looked already, but part of him felt horrified to think about what he might see in the reflection.



Ashley opened up the door effortlessly, and led Jeremy outside. She took him over to a lone tree in the front yard, and then she glanced away. "Alright, go do your business." She spoke with a hint of frustration in her tone.



Jeremy couldn't begin to describe how he felt. He was blushing immensely underneath what he felt like fur on his cheeks, something he couldn't quite see with his eyes, but he could feel. He could feel a lot of warmth on his body in fact, except on his tits, his asshole, and his cock, which dangled downwards out in the open, just underneath his furry tail. He looked up at Ashley with uncertainty in his eyes, but when she ordered him to do his business, he felt a rush inside of him reach his crotch. As he stepped outside, he felt a cool breeze brush against his new pronounced asshole, and it made him shiver. His anus just wasn't being shown to the world, it was incredibly sensitive! He felt himself grow hard just from that stiff breeze alone.



"Go, behind the tree, pee." Ashley said with a hint of annoyance in her tone.



Jeremy's ears lowered as he heard the command. He went behind the tree, and squatted. He felt his body relieve itself, and as it did, he felt stranger between his legs. He looked down and, between his many rows of tits, now at least at a B cup, his cock had vanished. He shivered as he felt a cold sensation touch his balls, and then he couldn't feel them at all. Had he been able to see what was going on, he would have noticed his cock and balls vanished, pulling inside of his body, and leaving nothing but a feminine, canine cunt.



Ashley waited for Jeremy with her face turned away from him. "Alright, now that you've gone...god I don't know...I'll take you shopping I guess, get some pet food...and then try to find out where Jeremy is maybe."



Jeremy's ears flickered as he heard Ashley. His tongue lolled out of his mouth, big and floppy, and he slowly panted. He remembered something about dogs and sweat glands, but he couldn't recall what it was exactly, and while he was panting, he could feel sweat matting his fur down too. I don't want to go out like this! He thought to himself. I'm Jeremy! What can I do to show you that! He wished he could do something, anything to tell her. His speech was still heavily limited, especially since Ashley said he had to be quiet Jeremy looked at his sharp paws, paws that he swore looked larger than what normal paws should be, and then he hatched a plan. He started to scratch down a J on the grass.



Ashley didn't give him any time to write down more than that. With a tug, she pulled him towards the house. "Let's go slut puppy." She ordered by the name on his collar. "I guess if that's what Jeremy wants to call you, that's what we'll call you."



Jeremy hated the name, he wished to know who even made that collar if it wasn't him, and it wasn't Ashley. With his head low, he walked with her back inside. He could hear his short claws tap the hardwood floor with each step. His tail went low, and he could feel his multiple breasts sway with every step. It was an uncomfortable feeling that made him feel strange between his legs. He couldn't get an erection anymore without a penis, but he felt a growing heat that was getting bothersome.



Ashley led Jeremy into the bathroom, and she started to undress. "I'm getting changed first, then we'll go." She said with a sigh. "Stay. I'll only be a moment." After fully undressing, she tossed her clothes into the laundry basket just outside the bathroom, and then went into the bedroom to grab herself new clothes.



Jeremy watched Ashley until she left the room. Once she was gone, he immediately tried to move, but his legs felt as if they were stuck inside concrete. He could sit much like a dog could, he could stand, also just like a dog, but he couldn't raise his paws up off the ground at all. He couldn't even slide them around. As he was looking around the bathroom, he noticed a full length mirror hung onto the wall, allowing him to see his reflection. She thinks I look like a dog, but I know I'm not! I have all of these tits. No dog has tits like these. He thought to himself. He turned to see what he looked like, and his jaw dropped.



Jeremy saw, not the dog that he knew he looked like, but a dog that resembled a Labrador, without the many rows of tits dangling down. Jeremy stared at the reflection that was of a dog, and then he looked at himself. He had the same short dark fur, slight muzzle, pointed ears, short furry tail, and paws, though when Jeremy looked at his own paws, they were larger than the ones he saw in the mirror. He had more questions now than before. He could only think that someone was doing this to him somehow, but he didn't know who. Did I make a wish or something? All I did was find a damned collar! He thought to himself in a panic. Maybe if I go back to the dog park I can find answers, but how am I going to get Ashley there?! 



Ashley returned to the bathroom wearing more casual clothes than before. She had a blue top on with cut jeans and white running shoes. She took a hold of Jeremy's leash. "Alright, let's go. Jeremy owes me big time when the car is going to smell like dog."



Jeremy let out a small bark when he was pulled. He walked with her, if only because she had ordered him to go, but he disliked it. He could feel his tits, growing heavier, and swaying all the more down on his chest. He could feel his anus and vagina grow both cold on the outside, and hot on the inside. It felt as if his tits, and his ass and vagina were the only parts exposed to the world, while the rest of him was covered in fur. He could still feel his body sweat too, matting down his fur. The sensation of heat in his vagina was stronger than the rest of his body. He could almost feel himself sweat on the inside, and it was just then that he realized that his new canine cunt was getting wet on the inside, so much so that it was gently dripping, and his ears could pick it up.



Ashley took Jeremy outside again, and then she looked around briefly. "I guess the pet store isn't very far away, it is right next to that stupid dog park isn't it...?" she looked down at Jeremy. "Alright girl, let's go." With the leash in one hand, and a cell phone in the other, she walked along the concrete path with Jeremy at her side.



When Jeremy was outside again, he was now slowly realizing all of the new smells he could pick up. His eyes were the same, but his nose had been enhanced. He picked up the scent he had just made on the tree earlier, he could smell someone cooking popcorn two houses down, but he could also smell something else, a scent he couldn't even begin to describe, but it made his many rows of nipples erect. It had a sort of musky smell to it, like a man that hadn't showered all week, but the smell was actually good to him. His tits continued to grow and swell, growing so big they brushed up against each other with every step, making him uncomfortable with walking, but what made it so much worse was the scent he picked up was making his canine cunt drip eagerly, literally, onto the ground, following him as if he left a trail. He could feel a strong pleasurable sensation grow in his canine cunt, even though nothing but air was gently touching it in the first place.



It wasn't long before the two walked to the dog park. Ashley noticed that Jeremy was walking a bit slower than normal, and when she looked back to see why, she couldn't figure it out. To her, and to the rest of the world, Jeremy was just a normal female dog, a bitch. She took the time for slow walking to try to text and get a hold of Jeremy, though nothing she tried worked. It wasn't long before the two got into the dog park, and they walked along the path. The park had become slightly more crowded than it had last time, with dogs and owners, many of the dogs not on leashes.



Jeremy found his tail shifting up and wagging slowly. His senses were overwhelmed at all of the dogs. His heart raced, and his tits were so large at this point that his nipples were dragging gently above the grass, making him more turned on than he knew he should have been as a female dog. He could pick up the scent of what he identified as male dogs, male dogs that wanted to mate. He knew that his new body very much was eager to mate too. The thought of a male canine cock in his dripping eager cunt shouldn't have turned him on as much as it was.



Ashley noticed there were various dogs not on leashes. "Well, I guess it's okay if you aren't on one either." Ashley took off the leash for Jeremy. "Going to be weird when I call for you slut puppy, but hey, go on and have fun for a bit. I'm going to try to keep contacting Jeremy, then we'll go shopping after this."



Jeremy felt the leash unclip, though his body felt frozen. It was hard to move as it was. Every step brushed his nipples onto the grass, making him more and more aroused, and he could tell there were male dogs approaching him. He wanted to yell at them to stop, but his body wanted it, it NEEDED a male dog for his bitch body. As he thought about another feral canine cock in his cunt, that was enough to drive his body to a small orgasm. He shivered, and let out a light whine as his four legs trembled, struggling to keep up his body. His canine cunt gushed out a wave of his canine juices that hit the ground like a small waterfall. He couldn't deny his sensations; he was in heat, he could very much tell that, his body needed puppies, and he had a feeling that he was going to be getting some very soon.



Ashley helped herself to an empty seat on a nearby bench. Once she sat down, she turned to the side and noticed a strange dog collar. "Huh?" She picked up the collar, and looked around to see if someone had lost it.

Once she held the black collar in her hands, a voice told her that she should try it on...just to see what it would be like.
