DOG OWNERS: What is your opinion of Purina Pro-Plan Selects?

I have never been fond of Purina products but I know a ton of people who's dog do very well on on it. If your dog does well on it, that's all that matters. Hip Dysplasia is hereditary, so I doubt that your mixed breed dog will not have Hip Dysplasia because of a supplement. It won't hurt, but it won't prevent it.
