I would like to look at some good sites or books, or schools that any of you may know for getting your trainer certification. I am reading some books, and I want to take my time, but I just wanted some opinions on some good places that you may have heard of. I know some of them can be expensive, but I am willing to save up my money to do it. Please let me know any advice, facts, opinions, etc. that may help me along the way. I have been interested in this for years now, and I really want to try to get all the information I can to make an informed decision. I would like to do this, and maybe also dog walking, or dog sitting. Thanks for everything!
