I have a quick question for other experienced boxer owners. I have a 10 week old male pup (Gus) that was playing with one of his littermates the other day! They played hard, and they were around some tile that caused my little guy to do the splits a couple of times. When he got home he crashed, and was exhausted....which I knew would be normal! That night though he seemed slow to get up, and reluctant to run when we took him outside, which wasn't like him. The next morning he still seemed tired, his gait was OK, normal energy at work with me, he can jog (so to speak) without difficulty, but when he wants to run it seems like he does a little bit of a bunny hop. Of course when I read about bunny hopping everything points to hip dysplasia. I called the vet and they said to give him a couple of days becuase he may just be sore! Should I be concerned......of course now I am driving myself crazy reading all of the stuff on hip dysplasia, and watching him non stop analyzing his every move! Has anyone else had this experience with a pup?
