re: Anyone had a young dog with hip dysplasia?

Yes. Had an English Bulldog born with it. She romped and played as a puppy. She then couldn't move her legs. As she aged and her muscles grew, she didn't seem bothered as much. She lived until she was 13. No surgery. The vet had a Weimaraner with the same. He said, they adjust as they age. Mine did. Your dog should be fine.
