Yeah, my dog hates when he can't reach us or if he's inside and we're not. He gets so upset. I bet that is what is going on. That is awesome your dogs were bale to be trained I hope he gets his freedom soon too but it sounds to me like they are just keeping him tied up and just expecting him to automatically know how to behave (i got that from when one day chicks were on the other dog and they let him loose) rather than actively working with him to help him behave and in that case he may never get free
My two dogs are the same. They need to be near me all the time. And I treat them like Princeses lol
It broke my heart to tie them up during their chicken training. I hated it as much as they did, but they are smart and worked out pretty quickly what I expected from them around the chookies. They will never have to be tied up again thank god!
