Here are some book recommendations you may be interested in. As with most books, it's like eating fish; eat the meat but spit out the bones. Some of it may not be useful or applicable for your situation but there's a lot of helpful material here as well.

I recommend this a lot because people anthropomorphize their dogs and it's good to relearn what or how a dog thinks and communicate in their language. As with many dog books you’ll have varying opinions about how to handle your pup. I think there’s a lot of insight in this one to help you consider your approach and what things to pay attention to and the “language” you or family combined may use to communicate to him or her.. It’s not a training book per se, and is somewhat redundant but I think it helps to foster better relationships with your fur friend.
