Don't like my coat!

Jonty really doesn't like his coat. I have to get his lead on so I can hold him before I get his coat or he would run upstairs. Even then he tries to pull away to go into a corner when I get it out.
It is obvious the rain is not going to ease and it was already after 0930 and he hadn't 'done' anything so off we went in the rain.
The coat doesn't hinder him at all, he still trots along and does whatever he needs to do and even had a little run in the park so I don't know why he dislikes it so much.

Back home, rub down of the head, belly and back end to dry off the bits the rain had reached and he's fine again.
