I was just looking at the 2009 list of most popular breeds from the AKC. It seemed like half the list was pretty big dogs and the other half was very small dogs with no medium sized dogs in between (well, maybe the beagle). I noticed that of the top 5 (lab, golden, Yorkie, GSD, and beagle in that order) that three of them are pretty large dogs. As a matter of fact, with the exception of the yorkie, three of the top 4 are dogs that get 70-80 lbs plus easily. Why do you think the trend is toward larger dogs?
