Stuart Little is a very loving, very attached dog to his human, but it takes a like time for him to  greet to know new people and is nervous around new big people, and it seems especially men. He's a guard dog in a tiny package, likes other dogs and is not a big fan of cats.  He's in a home with 5 cats right now and isn't a danger or a creator of problems, but he does try and exert dominance over the little naive one who wants to be his bestie. He's still decompressing from his ordeal of abandonment,  but it's been lovely watching him settle in and relax in a home
