I have a rescue Collie, I've had him coming up on two months. At first, we'd walk 2.5 miles each morning and another mile or so each afternoon. One morning several weeks ago, on our normal morning walk, about a block into it, he had already pooped once and peed several times, he just stopped dead in his tracks and froze, did not want to go on one more step. The only direction that he would willingly go was back towards the house. This has happened several times, at various places on our morning walks. Sometimes, I can wait a bit and he may change direction and want to head that way, other times I would give him a tug and he would go on, sometimes repeating the stop thing in another 50 yards or so, sometimes not. This morning, we got 20 feet from our front door and he locked up solid, only wanting to go back in the house. I waited, and led him in a different direction, going behind our house, and starting down a quiet ally, thinking that might make him feel better. No. In 30 yards, he froze again, and just wanted to go back home. I could bully him, and make him go, but I've always looked at these walks as being their time, and if he hates, or (as I suspect) is frightened of the idea, that's not fair to him, so I indulged him and we returned home. He didn't even want to go out in the back yard, clearly seeming to be frightened by the idea. Someone, please give me some insight on this, I've never seen a dog so traumatized about something that they should be looking forward to? He's physically healthy, his joints and paws are good, no issues.
