Howdy was a stray and his family never came for him. He is about 10 or 11 years old, up to date on all of his vaccinations, neutered, and micro-chipped. When we tested Howdy for heartworms, we found that he is high heartworm positive and that he will have to go thru treatment, so sad since preventive is really inexpensive next to the cost of the treatment. Howdy is 16 inches tall and weighs 38 pounds, he needs to lose a few. Howdy is a true Texan, very friendly and he greets you with a paw (handshake).
