http://www.instituteofcaninebiology...ant-things-to-know-about-canine-hip-dysplasia I thought this was a good article. It emphasises the importance of not letting a puppy become overweight (and yes I appreciate the irony of me flagging this up, when I struggle to keep Molly at an ok weight) and not supplementing diet with additional vitamins, minerals etc. I think the doggy world has gone overboard on the restricted exercise rule for puppies, whereas weight seems to be a much bigger risk factor for hip dysplasia.
Thanks for sharing, Joy. I thought this point was especially important: "Signs of lameness usually first appear when the puppy is 4 to 6 months old, but after a month or two the dog will often seem better. This is because damage to the acetabular rim such as microfractures will have healed and the dog is no longer in pain, but development of dysplasia and osteoarthritis will continue. From there, the dog might not display clinical signs again for years while the pathological damage progresses."
Thanks for sharing @Joy . An interesting article which I think really supports the advice we give 'if your young dog is limping go to the vet'
