I've observed numerous times, on dog shows like "Ceasar 911", the use of treadmills to "rehabilitate" animals with behavioral problems like aggression, constant barking and manic issues like licking and tail chasing. As I've said several times before, here, these "dog shows" are more about people (who own dogs) than about the dogs, themselves. Dogs need to move; it's written in their DNA. It's the culmination of a million years of evolution. Just because some schmuck, 1000 years ago, put a leash on a wolf, started feeding it, then, decided I'll "domesticate" this fella to keep me company during cold & lonely winter nights does not alter an animals physiological requirements. Wolfs have to hunt. Killer Whales have to swim. Pembrokes got to run! Nothing demonstrates how little most dog owners know about the needs of dogs (particularly, pems) than the use of treadmills on these shows to "correct" unwanted" or dangerous behaviors in dogs! Sometimes I think to myself, "Am I the only one who sees what's "going on", here???...", when it comes to exercise and how huge an affect it has, not just on physical fitness, but on a dog's behavior and emotional stability, too? And, to take this one step, further, how uneducated and unprepared most parents are in establishing healthy diet & daily exercise as the "hub of the wheel" in child rearing and that education at the expense of physical fitness and developing social skills results in adults that are severely limited both mentally and emotionally (and prone to potentially risky, bizarre, dangerous or violent acts). The point of this post: Please don't buy a treadmill for your pem. 1. Walk your damn dog, and... 2. Drag all your kids with you! PS: Why do people refer to Pit Bulls as an "aggressive breed" but never say the same for alligators? If Chihuahua's had the bite strength of an angry hippo and they were raised by a self-absorbed, moron for an owner, trust me, they would be considered an "aggressive breed", too.
