SuperWanda, I hope you have a diagnosis by now. Decisions would be easier if you know what you are dealing with. It must be so frustrating and worrying.
I am posting a photo of Arie's belly. His groomer took one look and knew what she was seeing , but how unfortunate are we Aussies that her qualifications aren't enough here? She shouldn't be wasting her talent as a dog groomer. I know the owner paid a huge price and was determined to save his precious dog, but really that vet/groomer probably saved her just by alerting him. Scandalous that she can't practice here.
Fingers crossed for Timber, whatever ails her.
