I wish that there was more content to the book, though. Perhaps 75% of it is filler. There are whole chapters on feeding, medical care and basics like sit, down and stay. Certainly, all of these topics are important, but they have only tangential relevance to trick training.

There are several other filler chapters about dog sports. Why fill 50-odd pages with brief overviews of skijoring, carting and flyball? Each of these sports has more than a few good books that readers can refer to if they're interested. Being a Border Collie owner in Texas, I have no use for info on the Iditarod!

I would much rather have a smaller volume filled with stuff that I want to read. All of this filler dilutes the book, and makes it harder to pick out the valuable info.
