I think that chaining your dog (if done properly) is just fine. They look well cared for and loved. Like others have said, there is a right way and a wrong way of doing things and you have obviously chosen a the right way. It is against the law here now for anyone to chain their dogs outside. I like to have my dogs inside with me, but as many problems that can occure, I can also understand why people have their dogs outside. I too have had dogs outside and never had a problem.
