I am a dog person. I playfully postulate that there are two basic sets of humans: dog people and non-dog people. If you are a dog lover then this article by David Hochman in the Sunday Styles section of the New York Times is worth reading. The thesis is that dogs are far smarter and more capable than many people realize. For instance, a 9-year-old Border Collie in South Carolina may know up to a thousand words. Another dog in Japan is capable of detecting early stage colon cancer at an astounding 98 percent success rate! The next time you are tempted to believe your dog is stupid, you might want to put a little time, energy, and money into training him or her better. Much like humans, the more stimulation we give our pets in terms of memory and learning the better!
