You will never meet a dog quite like Rusty.
He is soft and cuddly, but don't ever let him hear you say that because when you first meet him he will pretend not to like you and act as tough as he can. In reality he is a very insecure dog who puts on a front to keep people away. It takes time, but once you gain his trust he becomes sweet and full of personality.
He will always have a strong personality and think he is king of the castle so he would need someone with very good dog skills and who can understand him. It is a long process, but so worth the journey.
He can live with other dogs, but is very selective who he shares his home with and would likely have to live in a managed home of some kind. Don't let all this fool you because beneath his tough guy exterior lies a sweet, silly little guy who, once he let's his guard down, would make a great companion. He does require relationship building and multiple visits so he would need a patient and understanding person.
