Jack Jack is a 4 month old Border Terrier Schnauzer mix who is the life of the party but also a sweet little soul who loves to snuggle. He plays with toys and other dogs well. He is good with cats, dogs of all ages and guinea pigs. He is crate trained, can sit and about 80% house trained but like all 4 month old puppies will need your continued support and training. Jack is the smallest of the litter & just an all around great little dog.
