After a year 1/2 of treating my beautiful Golden at another hospital for yeast ear infections and "allergies" I found Dr. Sam. My dog had already developed a tumor due to severe infection on the right ear and was probably going to lose his ear canal entirely which he did after the surgery. His left ear was saved and with the medication and treatment he gave us! I can not believe that the left ear is healthy !! within 2 weeks of treatment. Unfortunately he found another tumor that is now malignant. After having him treated at another Vet Hospital and I can say that Dr. Sam its very professional and he saved his left ear. Unfortunately now I am dealing with other serious issues non related. I recommend him. He knows what he is doing. !! He cares.
