Jack (for those of you that don't remember, as I haven't been on much), is a 4 year old male lab.
A friend of mine runs a small rescue, and has a foster that is a female pit mix roughly a year old. She seems to be a bit rude--within seconds of sniffing Jack at their first meeting she was standing on his shoulders and growling. She eventually seems to want to get him to play with her, but she has a very rude, bullying manner about her at first.
This last interaction they had she pretty much greeted him growling. He ignored her when she growled and followed after me. We went to let them out in the back to go potty (it's a large training facility with a large indoor and outdoor play/training area) and they sniffed a few more times and seemed OK. Then the female got in Jack's face and growled again, trying to put her front paws on him. Instead of turning away and avoiding (which he had been doing when she had been rude before), he kind of held his head high, stiffened, thwapped her front paw down with his own and showed her his teeth!
After that she backed down, and he proceeded to do his best to ignore her-turning his head or whole body from her if she got near him, sometimes putting myself or DH in between him and the female. She didn't try to bully him the rest of the night and he did his best to not acknowledge her presence. At one point after she left him alone for a while he did seem interested in playing, but she became very growly and rough so he did the ignoring thing again.
I never got the feeling he was in danger--I think she was just being a buttface. Should I have stepped in when the female began to get pushy, or was it a good idea to let Jack handle the interaction himself??
