This is Colby! He’s a Jack Russell/Chihuahua mix. 3-years-old. No history of aggressive or reactive behaviors. Colby came from a puppy mill when he was a pup. Accidental crossbreed litter. We aren’t sure what he witnessed or experienced but he is terrified of men and young children. He shakes and cowers. I am desperate to find someone to take him in and show him not all humans are bad. You’ll need compassion, patience and a willingness to help Colby. Neutered, crate trained, house trained, OK with other dogs and cats.
