We all make or have made mistakes with our dogs, gosh I can put my hands up to that. Although I have never read Jans books or seen her on tv she obviously is great at what she does, it is very hard to get into others minds on how an individual trains there dogs as Jan has taken years to become good at what she does and for others to read one book or so and digest it all to become as good as her or to understand 100% is impossible.
I dont think anyone should be negative towards anyone who trains dogs professionally as they are all good at what they do, if they were all the same it would be heck of a boring, also as someone else said, I take bits and pieces from lots of people to train my dogs to do what I want them to do. I dont read books I go out and take on board hands on experience.
Alot of people including me at times forget dogs are dogs and this is when problems arise, its not the dogs its the owners and I hold my hand up to that also.
The way people train dogs is changing all the time "Why" My dogs aint any different to the dogs my mother had when we were all young, she never consulted a dog traininer, her dogs respected her and did as they were told just like we did.
Before I went on to get other dogs, I did my reasarch for 2 years before getting another dog covering all aspects of training and so on, consulted traininers, vets and breeders to make sure I did not spoil a perfectly good dog. I found it was me that needed the training and not the dogs.
