My lab, now at 7 started terrible itching and I could see he was destroying his skin. We took him to the vet, as I couldn't stand watching him so uncomfortable. The vet feels he has developed allergies, and suggested an allergy test. Didn't think twice about saying ' do whatever you need to do'. It was a $690 bill for testing and meds. We are still waiting for the results but within 2 days, I received an email, and 4 days later, received my check. I know Whatever it is, I don't have to worry about cost!
