He's a great teacher and has taught tons of people to be confident around their dogs and master of their pack. I will agree that his methods are not for everyone, but if you're able to see your dog as a dog and not a human it should be much easier to follow his practices. I was brought in a house that breed Labradors and I've been using a lot of the alpha techniques since I was a child and will stand behind them 100%.
I will say that Bulldogs are much more work and Boris has been the toughest pup I've worked with. He does a great job with me around, but the second I'm gone he does what he wants and nothing else... He isn't aggressive or anything, but he'll just sit and stare at you thinking "silly human". This really upsets my girlfriend so we've hired a trainer to come out and help... (I'm waiting to say I told you so )
Glad to hear an update on Chubbs and hope your kitty feels better!
