Explorer was one of 4 seniors we took in from a puppy mill case. He's a fearful little guy who hasn't had much human interaction, but has never offered to bite . Being a puppy mill senior this guy will need some love. He is not potty trained and will not come to you. He is scared but coming around very slowly, and was recently neutered. Explorer is the youngest of this group, and we would consider foster to adopt because of his special needs.
