We've got a 7 month old lab puppy and have been training his recall since the first day he came home. Up until about 2 weeks ago, it was going really well and his recall to the whistle was very reliable, but now it's going downhill.
I know it's a phase related to his age and levels of excitement, but he now goes selectively deaf to the whistle when there are other dogs he wants to play with. He's super friendly and well-socialised so I have no fears that he would ever hurt anyone or any other dog, but he's a big bouncy puppy and other dogs don't always appreciate that. Previously, if another dog gave him a telling off, he'd just happily leave them alone and trot back to us but now he just runs rings around the dog/s and their owners until I can find a way to intervene and get him back.
Sometimes other things work, like me instigating a game of chase (him chasing me) or fetch to lead him in the other direction, but that's becoming less and less reliable as well and now that I'm heavily pregnant and suffering with SPD I can't keep up with him or physically intervene as easily.
Has anyone got any suggestions? We use a high value reward for recall that he only gets for that and heel-walking. We practise all the time, but I know we're fighting a tricky developmental phase. He's not sufficiently motivated by other things like toys/retrieve games so that's a non-starter for now. I'm also loathe to put him on the lead in the park because he really needs the run around and also I feel like that would be counter-productive because we need to train the behaviour out, not just restrain him otherwise the problem will never be solved.
Any wisdom greatly appreciated!
