You can’t force a large dog to do anything he doesn’t want to do - especially is he is Thor’s size. You have to try & outsmart them. Big dogs often look block-headed. This is not the case with Thor and outsmarting him is harder than it seems. He likes the fresh air and always wants to be in the outdoor part of his kennel. I was on my way out, heading home - I needed to close the little doggie door. But that meant that I needed to get Thor to come inside. I tried caling his name - no good, he knows better. I tried to give him a treat but he was fast enough to grab it and get out the door before I could close it. I tried getting inside his kennel and offering to rub his belly - not a chance - he simply stuck his head inside to get some petting, but refused to bring his body all the way in. I tried another treat - no way - this time he laid down outside and draped his head through the little doorway to get the treat, but would not even stand or sit up for the snack. This guy knew all my tricks before I knew them. I finally gave up and let him have his way, so he could be outside for the evening if he wanted. No doubt, as soon as I left, he probably sauntered inside and fell asleep on his bedding. I went home and wondered how a dog had outsmarted me. Anyway, if you want a smart, funny, loveable dog - please think about Thor. He is truly terrific.
