“You sure ya gonna be ok Spike?” Asked Applejack as she put her bag into the family wagon.
Her and her family were getting ready to go to the next Apple family reunion.
After how stressed out Applejack had gotten planning the last one, she was happy cousin Braeburn had offered to host it this year in Appaloosa.
The barn yard animals would be fine for a few days, their food being able to be put out ahead of time no problem, but Winona was going to need to be let out and feed a few times a day.
Luckily Spike had been happy to volunteer, offering to stay and keep the dog company while they were away. He even offered to stay on the sofa to ensure Winona wouldn’t get lonely.
“Don’t worry Applejack. I got everything under control. You guys just have a fun time in Appaloosa ok?” Said Spike.
Applejack took her spot in the wagon beside Granny Smith and Apple Bloom.
“Well alright then. Just don’t forget her pills once a day. Just mix it into her food.”
“I got it. You don’t have to worry about a thing.”
The Apples waved goodbye to Spike as they pulled away from their farm, Big Mac pulling the wagon out of town and toward Appaloosa.
Spike waved back until the family was out of sight, then turned and faced Winona, who had been wandering around in the front yard.
“Looks like it’s just you and me this weekend girl.” He said, reaching his clawed hand down and petting her head.
Winona wagged her tail and pushed her head against spikes hand, happy to receive the affection.
The two spent the next hour playing in the yard, with Spike throwing a tennis ball and Winona bringing it back.
Soon though it was time for lunch and they both made their way inside to get something to eat.
Spike had been happy to volunteer to watch Winona while the Apples were away.
He was happy to help out a friend, and besides, a long weekend alone with just Winona to keep him company was a nice change of pace.
He brought his bag with a few comic books to read as well.
He made his way to the kitchen and prepared his lunch, a sandwich with a few gemstones.
He then began preparing Winona’s lunch.
Her dog food was on the counter with instructions.
First he put two scoops of dry food in, and then put some wet food from a can. All that was left to do was mix her pill into it with a spoon.
He picked up the bottle of pills and tried to twist it open, but it wouldn’t budge.
He tried harder, using all of his strength to try and open the bottle.
This lead to the lid popping off in a quick and uncontrolled motion, sending pills flying all across the kitchen counter and floor.
“Aw man. Now I gotta clean this up.” Grumbled Spike, setting to work and picking up all the pills on the counter and floor.
Little did he realize however one pill had flown at the perfect angle to land right inside his sandwich, blending in with the rest of the ingredients and going unnoticed to the annoyed dragon.
After a couple of minutes, Spike had all the pills back into the bottle except for a few.
He decided to just leave them to the side on the counter to avoid a repeat of the disaster.
He mixed the pill into the wet food and sat the dish down on the floor where it had been before.
“Come and get it Winona!” Said Spike, the dog coming over and gobbling down her food.
Spike then grabbed his plate and sat down at the table, biting into his sandwich.
He ate every bite, enjoying the mix of greens and crunch gems.
Soon the sandwich was gone, spike licking his lips.
“Man that hit the spot.” He said.
He then went and sat in the living room, pulling out a comic to read.
Winona came in and joined him, plopping down on the couch next to him.
Before long, the day had winded down and it was now the evening.
Spike had gone through a good number of comic books and was about to pick up another when he heard his stomach growling.
He looked over at the clock.
“Five thirty. I think it’s about time for dinner. Don’t you girl?”
“Woof!” Barked Winona in agreement.
Spike got up and walked back into the kitchen, preparing a gemstone salad for himself and then began preparing Winona’s dinner.
As he finished and went to pick it up, he stopped.
He began to wonder what the dog food tasted like.
He couldn’t seem to shake the thought from his mind.
He had to know the answer!
He looked around.
There was nopony there but him and Winona.
Nopony else had to know.
He stuck a clawed finger into the wet food, bringing a small bit into his muzzle and sucking the food off his finger.
He chewed the food up and swallowed.
To his surprise, the food tasted wonderful!
It was one of the best things he’d ever eaten!
He began to eat more, grabbing bit after bit with his hands and shoving it into his mouth.
Before he knew it, he had eaten the whole dish clean.
When he had finished eating, he looked at the dish, shocked. He hadn’t meant to eat that much!
Winona had wondered over to his side, having watched the spectacle unfold and was giving the dragon a puzzled expression.
“Sorry Winona, I don’t know what happ- *Burp* Woof!”
Spike’s eyes widened. Why did he just bark? Was he going crazy?
No. No that couldn’t be it. He was fine. He just needed to get some rest. The early morning rise to get over to Applejack’s must be messing with his head.
He went to the bathroom, grabbing his toothbrush along the way.
As he walked, he found himself beginning to feel unbalanced, like his legs were having trouble supporting his weight.
He stopped in front of the sink, taking a moment to try and regain his balance and looked at himself in the mirror.
“It’s alright Spike. You’re ok. You’re just tired that’s all.”
It was then he began to feel his body tingle all over.
“I’m ok. I’m-” Spike stopped mid sentence as his nose began to darken, turning black right before his very eyes.
“That’s ok. Probably just an allergic reaction.” Said Spike, going into denial and not wanting to admit something was quite wrong with him.
It was then that he felt his legs give out, falling to the floor on his hands and knees.
He groaned as he felt his muscles begin to change.
His arms began to feel stronger, shifting to support the front half of his body better.
His hands changed, his fingers drawing into his palm slightly and curving. Callus like pads expanded out from his fingers and palms.
His feet followed suit and became smaller like his hands had.
He legs bones changed, going from straight to curved in the back.
“That’s ok. Now I can get around faster. Must just be puberty” Said Spike, knowing full well there were no quadruped dragons.
His thick and burley tail receded into his butt, disappearing before sprouting out a second later, now thin and sticking curved upward toward the ceiling.
It was then his scales began to be replaced as tufts of fur began appearing randomly all over his body, turning his rough exterior into a soft and fluffy one.
As Spike’s face and head spikes began receding, he had to finally concede.
Something was really wrong with him!
“Ah! I’m changing! Somepony help! Twilight! Something is wroooo-Woof!” Exclaimed Spike.
As spike let out a bark, his changes had completed.
A tuft of green head floof had sprouted out where his head spikes had been.
The spikes that ran down his back to his tail were also gone.
Two green, fur covered, floppy ears had formed on the sides of his head.
Spike was now a dog, just like he had been when he went through the magic mirror with Twilight.
Only now much more had changed.
Inside his head, new thoughts and instincts were coming forth in his subconscious.
His mind thought much simpler now, his mental capacities that of a real dog.
Spike took note of his surroundings.
He had felt scared a minute ago, but couldn’t figure out why.
Oh well! He felt nice now.
He noticed a smell in the air.
His new and stronger smelling nose followed the smell to another dog that seemed to be looking at him curiously.
This smell told him this dog was in heat and activated other instincts inside his mind.
He walked over and began licking Winona tentatively as he made his way toward her rear.
At the same time, his cock began to emerge from its sheath.
Where a girthy and bulbous dragon dick once sat was now a lengthy and slick doggy cock with a knot at its base.
Winona began to act upon her own instincts, submitting to Spike and presenting her ass to him.
She wasn’t sure what had happened to her dragon friend, but now there was a sexy stud here that was ready to fill her aching pussy. And she wanted him!
Spike took his position, grabbing Winona’s hips and positioning his rod at just the right spot.
He thrusted in, entering inside her and began to thrust.
Both dogs panted and moaned at the pleasure they were receiving.
Spike’s cock continued to explore deeper and deeper inside Winona’s passage, her walls hugging his cock in its warm and slick embrace.
Soon nature took its course and Spike could feel himself getting ready to cum.
He plunged himself as deep inside of his new mate as he could go, pushing his knot inside of her and cumming thick hot ropes of doggy cum into Winona’s womb.
As the two lay on the floor panting, Spike gave Winona some loving licks that she happily returned.
The two dogs stayed in each other’s embrace, enjoying the others company as they waited for Spike’s knot to recede back inside his sheath.
As Sunday evening rolled around, the Apple family came down the road to their farm in their wagon, all smiling and laughing from Granny Smith’s latest story.
They all had a wonderful time seeing their extended family, but it was good to be home.
Applejack got down off the wagon and went to go inside and see Spike.
Upon opening the door, the sight that greeted her was not what she expected.
Dog food lay all over the floor, in the living room pillows were torn open with feathers everywhere.
Things were knocked over onto the floor.
What in the heck had happened in here?
She didn’t have to wonder for long, as two dogs came running to greet the orange farm pony.
Winona and a purple and green dog hooped up at her, putting their hind legs against her chest and licking her face.
“Spike? Is that you? What in the name of Celestia happened to ya?” Asked Applejack.
Spike only barked excitedly at Applejack, his ability to speak long gone.
Applejack went to step back when she felt her hoof bump something on the floor.
It was the bottle of Winona’s pills.
Spike couldn’t have somehow eaten one could he?
They were pills designed to help regulate a dog’s hormones when a female came into heat.
They must have somehow turned Spike into a dog!
As Applejack struggled to process what had happened, Apple Bloom came in from outside.
Spike ran up to great her, giving a playful bark.
Apple Bloom looked at Spike.
“Is that Spike?” She asked placing her bag down.
“I think so. I better go find Twilight. Can you keep an eye on him and get this place cleaned up?” Applejack asked.
“Sure sis. Just one question.”
“What is it Apple Bloom?”
“Can we keep him?” She asked, smiling as she petted Spike on the head, wagging his tail in delight.
