I just got Murray's allergy test results back. He is extremely allergic to dust mites, but the good news is that this seems to be his only significant allergy. The vet is going to show me how to give the shots at home, and I have started washing his blankets a couple of times each week. He tells me that allergy shots for dust mites have a pretty high success rate, so I am really optimistic about this. Just wondering about anyone else's experience with allergy shots...
