Border Collie mix, maybe mini-aussie. Jack is a little guy, about 25 pounds, 2 years old. very good on a leash, in a car, happy to be in his crate at night and likes his crate for resting during the day. Stands well for grooming and really wants to please. Jack is leery or new comers, but warms up fairly quickly. Jack is comfotable around men, and just pastes himself to your side, looking for attention and love. He is VERY good with other dogs. Right now he is with a 3 year old neutered male and a 5 year old lab female.
