Once in awhile I watch The Dog Whisperer. Often just to see some dog training because it's been a big part of my life, and to critique Milan as well. I've been disappointed with many shows but there was an episode last night that caught my attention and reformed my opinion of him. He made note of the fact that for some dogs - even large aggressive dogs - a prong collar is not the answer and will actually make things worse. He was dealing with a large and very dominant Husky and quickly realized the part the prong was playing in the inability to correct his behavior. When he used an improvised form of what I use predominantly, a slip collar (which he made from a leash - not the best way obviously) he showed an adaptability I hadn't seen in him before. As I and many others here have said many times, the best trainers are willing to try different things with different dogs and no answer is the one answer for all dogs. I use an adjustable slip collar (similar to a Martingale) for almost all dogs, but I have used prongs and I have used Gentle Leaders as well. I was gratified to see this episode. I hope you caught it too.
