Nope, I'm not going home!

There is a style at the top of our road with a gap beside it for dogs to go through and the last twice we've come back that way from our walk Coll has sat down and refused to come through. Pulling doesn't work and neither do his treats. He doesn't seem to care if I tie his lead to the post and walk down the road. It's quite tedious waiting for him to change his mind. I think I'll try pushing next time!
