He is tied because he is a working sled dog and he hates being contained in the house. It is super hot in the house and he would suffer more than if he is outside under his shelter. Riley our other dog attacks him if they come in contact. We are going to build him a run soon so this is just temporary and a cable run also for excercise. Even if he is tied outside he comes for walks and goes in the garden hose to cool down. I adopted him when he was 1 from a friend that had 14 sled dogs. He gave me Bear, a sled, harnesses, etc and a special dog house that is cool in the summer and hot in the winter. When he was born his parents were tied because he ran out of kennel space. Being tied is all he's ever known and is scared to go in the house or out of his area alone. This is only temporary and I really want to get him off the chain. Thanks for all the advise on collars.
