"Hush, you," Garnet said,

She was going to have to do something, though.  The dog was trying to bite...

Garnet took the dog down an alleyway.

Once out of sight, the dog struggled in her arms, breaking free.  It was suddenly growing...

Garnet watched.

It was now taller than she was, and semi-bipedal.  Strange patterns were in its fur-- this was indeed a dog-creature, not a wolf-creature, but what a strange thing it was!  It was still snarling...

...it looked female, from hints that Garnet could see.

"Hey, whoa whoa, I'm not looking for a fight. I just want answers," Garnet said.

"Chased me," she snarled in an inhuman, bestial voice.  "Attacked me.  Not looking to fight?  Liar."

"No, I just wanted to know what you are and what your deal is," Garnet said.

"You attacked me!  Liar!" she repeated, and she looked like she was getting ready to either run or fight.

"I just picked you up," Garnet said. "I'm sorry if I hurt you, I didn't mean to. I just want some answers."

"No!" the dog snarled.  "See what you are.  See how you treat others.  No!  You get NOTHING!"

"Fine then" Garnet said, starting to head back to school.

"So, uh, what happened?" John asked.  He was panting from running after her.

"The dog got all pissy because I picked her up and took her to an alley. Turns out she can turn into a humanish form and talk," Garnet said.

"...I think she thought you were attacking her," said John.  "Not saying that you were, but she might have freaked out over that."

"I'm not sure why, I mean, people pick dogs up all the time," Garnet said.

"Not feral dogs, though," John said.  "Pretty clear that that's what we've got here."

"Really? In the city?" Garnet asked.

"Absolutely," said John.  "Basically every city ever has feral dogs."

"I didn't know that," Garnet said.

"Yeah, we run into them a whole bunch," said John.  "Some even try to run with us when we, you know... let it all out during the full moon."

"Heh. If you encounter that dog again, could you try smoothing things out?" Garnet asked, before realizing. "We had better get to school."

"Sure," said John.  "Yeah, let's hurry!"

They ran!

Garnet ran as fast as she could.
