I visited several websites featuring her and her book(s) and cannot find a single disclosure about her training in the field of animal behavior. All it says is that she has "owned a number of dogs". Since so many here always tell folks to get a behavioral expert (I assume with CREDENTIALS) I wonder what those of you who give that advice think of this book and author? Or is the ownership of a number of dogs a qualifier for "expert" status as a trainer/behaviorist? That brings to mind, just what ARE the credentials for an expert "Behaviorist" or "Trainer" and how do they differ?
