I presume you mean a Cavalier King Charles Spaniel which I have(CAVY-Short-tailed rough-haired South American rodent !).What is your dogs hip score ? Vets do tend to make a big thing of HD & in very large breeds it can cause problems, but in smaller breeds it causes less problems because the dog has less weight to carry. I presume your vet has a good knowledge of X rays & HD-not many do. I use a different vet for X raying as good as my vets are they do not have the knowledge my X ray specializt has,
Depending on how severe the HD is there are several courses of action that you & your vet can take, hip replacement, fremoral head removal etc
I have a twelve year old BC with severe HD(scored 34:34=68 the highest score a dog can have is 106 )He has never had any problem walking exercising & is still very sound with no arthritis. He has had no medication at all & no operations either-he has never had any veterinary treatment at all for his HD. He is exercised free & never road walked & fed a natural high quality diet. I ensure he s never over weight. He is never lame I had him X rayed as I was planning on doing agility with him & I have all my dogs HD sxored at 12 months
The only things I have not done with him is agility & breeding
