I recently adopted a 2 year old male pitbull. After noticing a few health problems, I took him to the vet and she said he had a hyperextended muscle in his leg and prescribed him Deramaxx. I also own another dog and he does not like our new dog, but he isn't typically social. The pitbull was fine with him, until last night. I have had him for about a week now, and last night he tried to bite our dog and was being aggressive. Is this because of the Deramaxx? Please help, he is a great dog.

More than likely, it's due to not feeling feel from the hyperextended muscle. Pain can make dogs aggressive due to feeling poorly, and it could be that the Deramaxx isn't enough to help his pain. I would keep him separated from your other dog for now, and take him back into the vet in the morning for a check up.
