Unfortunately Benji was probable infected before you got him but was not showing clinical signs. He's adorable. This is a serious disease that can be life threatening. Please follow the treatment plan your veterinarian recommends. Thanks for using Petco Pet Education Center, formerly Petcoach to help you get answers to your veterinary questions.
