If you suspect your dog has HD please know the only way to diagnose is via x-ray.
No vet can diagnose HD just by:
1. Examining the dog
2. Pulling on the legs (which you absolutely do not want done on a growing pup) (if your vet tries to do this to your pup – many will on your first vet visit – please stop them immediately or they can do damage) I also suggest finding a new vet.
3. Seeing the dog move.
The x-rays must be done by a vet with experience in proper positioning. Most of you will not find your regular vet qualified to do these x-rays.
Proper positioning is very important. See this link:
Note: The Orthopedic Foundation For Animals is the only organization qualified to read the x-rays on pure bred dogs and give a rating of fair, good or excellent (or confirm HD). Your vet is not qualified to do this.
