My 2 german shepherd dogs suffered from severe itching since September 2010. It was very difficult getting to the root cause of their symptoms finally in April 2011. Pollen or mold allergy was first suspected, then food allergy. After many veterinarian visits and symptom treatment a visit to the recommended canine dermatologist repeated the skin scraping test (negative again) but he deduced that their symptoms were most like scabies. This treatment cured their itching. ASPCA Pet Insurance came thru with timely reimbursement to cover much of the veterinarian and medication expenses. The only dissappointment is that even after meeting my deductable the insurance covered only a portion of the remaining expenses. Despite this disappointment, pet health insurance reimbursement more than paid for the insurance premium so I believe it is very cost effective.
