My husband posed the question “Why do dogs tilt their heads from side-to-side when you ask them a question?” Given the dismal economy, roller coaster-riding stock market and less than encouraging news all around, I was happy to delve into the deep-seated meaning of the doggy head cock. I thought it would be a Wiki-quick answer. Over 20 websites and blogs later, here’s what I found. Some dogs, such as Spaniel Parker, have pendulous (meaning hanging down loosely) ears that obstruct sounds. Short story: Sound waves get muffled by their thick ears. The dog has to cock his/her head so that sound waves can pass through their big, heavy ear flap before reaching their eardrums. I also learned that high-pitched sounds get their attention because they resemble the noises made by traditional prey such as rabbits or chipmunks. I believe all of this. But, I also believe that dogs quickly learn to interpret words that have meaning to them. Parker’s favorites are food, treats, cheese and bye-bye. Just say any one of these words and he is yours. Anyone have any other words that drive your dog or dogs to frenzied happiness?
