Dog Whisperer

Having grown up a farm girl and knowing instinctively how to work with animals (domesticated and farm animals), I felt vindicated and happy to see how an older calmer dog keeps a younger more immature dog in line; teaches him to be calm. My older dog was always so patient and sweet and we felt he taught Casey the new puppy how to behave. Now that Roger, the older dog, has passed, Casey seems a little depressed and out of sorts, but I think she is also reacting to my vibe. I'd love to get her a middle aged dog that's good natured and loves cats, too. It seems like a tall order. I know some people don't agree with his methods, but realistically there are some pretty out-of-control animals that need a tighter reign than other animals. I haven't seen anything on the program that I really disagree with--as per his methods, but I've only watched it a couple of times.
