Dr Johnson is the smartest vet I have ever met. I have jokingly refered to him as the Dr House of veterinarians. I have had two dogs who have been granted additional years of life because of his expertise, and therefore my family has been blessed with more time with our beloved dogs. I would, and have recommended Blue Sky to everyone and anyone who needs a vet. From fillings, ultrasounds, and liver failure. He knows how to treat them all.
