Author's Note

Okey I have no idea why there are so many down votes.
To make it a bit clearer: Dash has the body and mind of a dog. She can only see what she's doing and what's happening around her, but has no control over it.

Chapter 1

Twilight's new pet

Her friends kept calling Rainbow Dash lazy, since they more than often saw her napping on clouds or trees. Twilight had gotten bored of the conversations and went to action. So she searched for the Pegasus and found her in one of Applejacks trees in the orchard. As always, she was sleeping soundly.

A smirk crossed over her face as she pointed her horn towards the sleeping Pegasus. But in the second that she was going to zap her awake, she was tackled by something furry.
And slobbery.
Applejacks dog must have smelled that she was here. Winona was always so happy to see friends of Applejack.

When she was finally free from the attacker, she noticed that the tree branch was empty now.

And she heard something whimper behind it.

When she carefully walked around it, she found the source: a little cyan dog with a colorful tail.

At first she looked shy, and maybe a bit scared. But the second she noticed that Twilight was there

She was once again tackled down.

And Winona joined in the fun again.

When she could finally move again, she was followed by the cyan dog with every step.

It became clear to her that she couldn't just leave her alone. She had to take Dash with her.

The first day

~Twilight's castle~

After Twilight brought her new dog home, she was lost. She didn't know a thing about dogs. All she knew was that they always want to play, can eat more than an army of ponys, are hairy and slobbery and are supposed to be the best friend of any pony. Now she stood there, Dash sitting in front of her with her tongue sticking out, happily smiling at her while she wagged her rainbow tail. Luckily Spike came down the stairs into the front room.

"Hey Twilight, you're back!", he said. "And...Rainbow Dash?", he added when he saw the cyan dog in front of her, turning her head towards him. The next second he was tackled by Dash, landing on the floor and getting licked all over the face.

"On no! Rainbow stop!", Twilight tried to pull Dash away from Spike, but stopped when she heard him laugh.

"Hahahaha Rainbow I like you too! Phahahahahaha!" Twilight just stood there and stared at him in disbelief. Finally Dash finished licking Spike and ran through the next doors through the castle, barking every now and then.

"Spike? Are you alright?" Twilight asked.

"Jeez Twilight, she didn't try to kill me you know. But could you at least explain to me WHY SHE IS A DOG?!" Spikes voice rose up all of the sudden as he stood in front of Twilight, throwing his hands in the air.

Suddenly there were crashing sounds coming from upstairs. Twilight and Spike looked at the ceiling. Twilight was the first who ran to the stairs, Spike followed. Twilight vanished in a flash of light and teleported herself in the room where still sounds of breaking things were. The moment Spike finally got on the second floor, he heard Twilight scream. This was bad. Did Dash destroy the room? Wait, which room was it anyways? He followed her voice.

"Rainbow Dash! Get here!!!" Twilight yelled.

Spike ran to the room. He froze at the sight. It was Twilight's working room. The desk, scrolls, books, all was shredded into pieces all over the place. Dash was hiding under wrecked pieces of the bookshelf. Either she was scared of Twilight or stuck. But either way, she wasn't going to fix this mess. It would become his job to clean up once again. He sighed.

"Rainbow Dash I'm warning you! Get here or I'll make you!" Twilight got angry.

Dash whimpered under she shelf. She was stuck. She couldn't move. It was just way too heavy for her small body. Twilight got angrier with every second, she could feel it. What should she do? She couldn't tell her.

So she did what what dogs do.

She howled.

Twilight got over to her, not paying any attention to the mess anymore. For some reason every anger she felt seconds ago vanished and she was concerned about her pet's well-being. She lifted the shelf with her magic, freeing Dash and levitated her with her while walking out of the room. Spike just watched the whole scene. That was...unexpected? He shrugged it off and went after them.

Twilight had placed Dash on her bed in her room, looking if Dash got hurt. Luckily she just ended up in some bruises and a lightly hurt hind leg. Twilight sat before her bed, looking Dash directly into the eyes. Spike watched them staring into each other's eyes like they were glued together. There was something off about this whole thing, wasn't there? He wasn't sure. Since the two didn't pay any attention to him, he just let them be and went to his room. It was getting late and he had to clean up the room Dash messed up tomorrow, so he would just go to bed.

Twilight laid next to Dash in the bed, slightly hugging her until she fell asleep. It felt so nice to finally have someone to sleep with, who was so fluffy and cuddly and...cute. Yeah, that was it. Dogs were cute, and Dash was a special dog. Twilight had a special dog. She drifted off to sleep, hearing Dash snore silently.

The next day

Twilight woke up from smashing and crashing and shredding sounds. Half asleep, she didn't remember what happened yesterday so soon, so she just thought Spike was in the kitchen. But these sounds were different. Then the memories came back. She touched her hoof around her. Nothing. Dash was gone!

Another crash.

Twilight teleported herself downstairs.

She followed the shredding sounds until she reached the library of the castle.

Then she saw the room.

Then she screamed.

"RAAAIINBOOOOW DAAAAAAAAASH!!!!!!!!!"
