When I first got this book I was so excited! Finally, a book that would talk about all different careers working with pets. But when I started reading it I realized that the book is about 80% on grooming.
If you want to be a groomer, this book is written by a true pro and is a wealth of knowledge for you, but for anything other business dealing with pets, it just offers some basic tips that you could find on the internet. The sections explaining other petcare businesses are too small and I feel they're just some token information thrown in to justify the title.
I personally am debating getting into pet store ownership, dog daycare or becoming a trainer and in my case this book was useless. There's excellent info on grooming, but I wish they had added some additional authors who are experienced with training, running dog day care services, dog walking services, pet stores, pet sitting, etc.
And theres a spelling error on the cover ("Write you own").
If you are looking for a book with information on becoming a pet sitter, though, this book contains only general information, much of which can be had online by joining mailing lists or bulletin boards.
