I walked over to the cage where a small, aggressive wolf puppy was sitting.

"So you're the one causing trouble for my people..." I muttered, then smiled smartly and reached out to pet you, but you immediately lunged at me, wanting to bite me. I saw this coming and before you could bite me, I grabbed you tightly by the fur on the back of your neck and pressed you against the bars of the cage, making you squeal.
"After the tests, you won't be so aggressive anymore," I said, smiling smartly.
