Hello, I have a 20 month old Bull mastiff and he starts limping on his right front Arm on and off especially after exercise.
Now here's the problem.. when he was around 9 months old he jumped out of the car window and then began temporarily limping It disappeared and came back on and off like now. like i said it usually happens after a long walk and good exorcise.
Anyway, i'm just wondering if it's delayed muscle soreness like humans get or could it be that exorcise is activating his old possible injury.. I never did take him to the vet for that. WHat do you think?
