My dogue has a cracking noise coming from her shoulder when she moves. Had her at the vet tonight and he thinks it could be Oesteochondritis of the shoulder. X-rays are planned for Wednesday so hopefully he will know for sure what the problem is then. I first heard this back in November but then it seemed to clear up with only the odd repeat, but over the weekend it seemed to be with every move she made so called the vet and he saw her this evening. Fingers crossed its not serious.
