I have a tendency to go way over the top sometimes. My wife calls me an extremist. So of course when we got Zoe, I started researching on the best food, how to train her, what would make her most comfortable...basically how can I give her all she needs and wants. I'm looking at books to learn more about her mindset and why she does what she does and what she needs me to do to help her be the best and happiest dog she can be. I'm on amazon and I've realized that I will spend hundreds of dollars easily with all the choices. -On talking terms with dogs -Cautious Canine (Zoe can be a bit fearful and sometimes too focused on certain things) -Other end of the leash These are the three I'm looking at now. Any other suggestions or something other than these three? I'm definitely getting a book on body language so I can know better what she is trying to tell me. I'm open to anything else.
