My 1 year old dog hates having his collar on. When he sees it he jumps backwards, leaps about and then rolls over on his back with his legs in the air (which I know is a sign of him being uncomfortable ) although it does look quite cute. He then just lies still and has his collar on, then gets up and stands as close as he can to me with his head down sort of frozen. Then has a shake and is happy and waggy again. Then he's fine and enthusiastically leaves the house for his walk or car trip.
I've tried giving him treats and taking the collar off and putting it on again and more treats etc,
I don't really want to leave it on all the time but it's getting worse trying to get it on him for walks. I never react to his antics or run after him, I just sit down and wait and he eventually comes over and lies down in front of me.
