Hello, my sister has a young German Shepherd (a year and a few months) and the vet said that he has hip dysplasia. I've only received this information second-hand, so I don't know exactly what the vet said. He is inbred because the breeding was an accident.
A lot of what I've researched on hip dysplasia does not match him at all. He has no pain or reluctance to get up and jump around. He seems to run just like any other dog, no lameness that I can see.
I mainly want to make sure that jumping with him now won't cause pain later.
Anyways, he seems to love jumping and I was wondering if it is safe to do it with him? Nothing too high, but I'd like to know what the maximum height/ length of the jumps should be for him. Jumping will be done on grass or turf, jumps will be able to be knocked down easily.
He weighs around 80 pounds and is probably a little on the taller side.

If jumping isn't safe to do, I need to know what other things I could do with him. He doesn't get as much room to run or walked as often as he should, so something that will take up more energy and less room would be ideal.
