[EX Q]: This book is short with only 26 pages. If your looking for a very basic overview then this would be fine but i think people wanting to understand economics will most likely get just as much from reading my blog.
[EX A]: Bad review

[EX Q]: It's ok to read but for a book about dog training it didn't seem like there was a lot of specific info or guidance. There is one very simple sentence that helped train my dog, and then it's the same things every week. Glad I bought it used. Good luck if you buy new. But this was helpful in some ways. We have a new puppy right now we needed help with potty training.
[EX A]: Bad review

[EX Q]: Great item, works great no problems after using this item.
