Gets along with children: No I have never seen him interact with children but because of his space/boundary issues I do not feel comfortable having him around children.
Gets along with other dogs: Yes Yes, but generally only bigger and older dogs. He does not like dogs that get up in his face, as he will respond defensively/aggressively. Because of this, I only let him socialize with dogs that I have approved beforehand.
Gets along with cats: Yes He was fostered before I adopted him with a family that had cats, and they reported him getting along fine with the cats.
