Next I made a skeleton for the dog. It's similar to ones I made in the past, however there are some extra things like the tail, ears, jaw and eyes. After that was done, I had to bind the skin to the skeleton. The book went over a brief lesson on what happens when models bend and how to fix problem areas.
The collar isn't a part of the main geometry and is just constrained to a position relative to one of the neck joints so it doesn't deform with the skeleton. This was causing some big problems but I was able to work the neck joints so that the collar doesn't penetrate the skin during bending. While making the model, I wasn't aware I'd be making a joint to control mouth movement. Luckily I put in enough detail in the mouth to work with and it was just a quick fix to the model to get it to open and close.
