They come in all shapes and colors and have been used in a variety of ways by humans for generations. Of course, we’re talking about dogs. For many of us today, a dog or two are an integral part of our family. They live in our homes, travel with us on vacation and even get a good portion of our ‘human’ food – even though the veterinarian told us not to feed them. The common adage is that they are man’s best friend. In many cases this saying is true. Dogs are loyal and don’t hold grudges. They comfort us when we are upset and make us laugh with the silly things they do. In many cases, too, they would protect us without a second thought about their own safety.
