I like the Dog Whisperer. To me there is something pure about working with a troubled dog and making them better, and Cesar Millan makes working with them look almost magical.
Another of the reasons I'm so fond of this show is that it promotes awareness for everyone regarding dogs. The cliche about bad dogs and bad owners isn't really true in my opinion. However ignorance and assumption are the mother and father of all fuckups. So a bit of entertaining education never hurts anyone in my opinion. If everyone, and not just dog owners understood more about canine nature and behavior then you wouldn't hear about cities banning pitt-bulls because they're supposedly a "dangerous breed".
So hey, check it out.
