I've had a Border Collie pup for nearly 3 months now (he's almost 5months) and we've just realized that he is getting too much exercise (around 2hrs per day including 30mins of running). I've just read up on the effects of over exercising on the hips of dogs and how it can lead to hip dysplasia. I am very paranoid that he might have hip dysplasia. He seems to sway a bit when he walks and he seems to have a bit of a bunny hop. However, he's been doing this since he was 2 months and I've heard it's normal for poppies? What should I do about this situation? I will definitely cut down exercise to just 2 daily walks of 30minutes (is that suitable for him?). Also, I'm planning to switch his food from puppy food to adult food as I've heard that puppy food is too high in calories and may result in hip problems. Is there anything else I should do?
