Hi I have newly adopted a 4 year old rescue Border Collie boy. He is very clever, funny and is running rings round me. Any and all help is welcome! He knows lots of commands already but chooses not to respond when it doesn't suit him. The oddest thing he does is when I go to let him outside (once we get out the door because that is quite the carry on) he stands outside the step and stares at you. If you turn and go back in he will stay and lie down still focused entirely. If you try and give him a command like be quick or go pee he ignores it. If you go out he tries to air bite or nip at you. Not to hurt but more to get you to do what he wants I think. This is just one of his little foibles. He also jumps up all the time, pulls like a train on lead, selectively dislikes random dogs, barks at people in hoods, if we walk with a group he will focus on the one dog who doesn't want to play with him and runs circles continuously around them. This isn't an exhaustive list. I know he sounds like a nightmare but he is an incredibly loving funny dog with me and my partner. My biggest worry is that I'm making these behaviours worse by trying to fix them incorrectly.
