So I am exploring ideas of training my 4 month old Yorkie. I came across the "Dog Father" Don Sullivan that raves he is the best. I am a bit hesitant because the training consists of using a behavioral collar. Being a new Yorkie Mom I am very leery of everything. I know I probably need to lighten up a bit but just can't help to be so overprotective, especially when I have been told that using a harness is best for the Yorkie breed because of the risk of a collapsed trachea. I love him more and more everyday but he does need some discipline.
Have any of you used the "perfect dog" training by Don Sullivan? If so, did you like it? Did it work?
