Not only does this strengthen the bond between the owner and pet, but with me as well.”

Dr. Read has two sons and a daughter. He also has two dogs, Sully the Cavalier mix and Ramona a Cairn Terrier mix. Dr. Read spends his free time attending sporting events, watching his children play sports, and going to the movies or working on new recipes.
