Hi,
Despite my avatar, I have a cocker spaniel and I have a pretty good idea what is your dog doing. Since winter started I thought we'll have to do with less walks since it was pretty much impossible to go out with a dog in a small snow blaze. The longer he stays inside, the 'crazier' he gets when we go outside. I was thinking of getting a collar just because of this problem. So now even if I'm dead tired I try to take him outside, at least for 10-15 minutes several times a day - or for few longer walks if the weather is OK. It definitely helps because I guess there is no way around dog needing to be active. I don’t think I solved this problem, I just find somewhat temporary solution, so hopefully someone else might have some advice,
Wish you all the best,
Nicole
