I'm not really sure, it sort of depends on what he was socialized to. He's fine wearing clothing, his Santa suit didn't bug him in the least and putting sun glasses on him went surprisingly well considering the fact that he likes to eat sunglasses. Nail clipping used to be a breeze until his clippers started hurting him because they were dull, so now he gets really nervous and freaks out a bit. I'm hoping we might be able to repair that. He is fine with me looking everywhere and brushing everywhere and fine with his paws being handled outside of clipping. He likes to be flipped on his back for cuddles. I brush his teeth with no problem. He enjoys hugs.
But I don't really know if those things are tolerance because he doesn't dislike them, I feel like tolerance is putting up with something you dislike. I don't think he's so great at that, luckily there aren't a ton of things he dislikes. He can be a resource guarder, his biggest "low tolerance" issue is being picked up or moved over when he's lying on the couch and he'll growl and snap. When I think about people who say "my dog doesn't like it but he deals with it" I feel like Tucker doesn't do that, if he doesn't like it he tries to end it, forcing him to "deal with it" may end in puncture wounds. All of the things he allows me to do he doesn't mind, so I'm glad he's been socialized to so much handling. If I want him to stop growling about being moved on the couch I'll have to make him like it more. So I guess he's not really tolerant, he just doesn't have issues with a lot of things.
