There's always that question. Are you a dog person or a cat person? I'm both. I've had both. I like both. I would like to have another of each at some point.
As far as breeds go, I'm far from a "breedist." However... I will say that I am partial to two breeds of dogs. Beagles and Whippets. I grew up with a beagle. My last dog was a beagle mix. Perfect size. I love the tri-coloring. Unlike a lot of people, I don't mind their baying. Whippets... I have never had one myself, but I've always loved their look. They have possibly the most expressive eyes of any breed.
When I lived in Virginia, I made it to several playdates of the local whippet group. I wish I had a better camera then... or more to the point, a better lens. Especially when they were doing their coursing runs. SO fast.
I've looked into some dog shows in Las Vegas. But it seems like the dominant breeds here are Chihuahuas and Pit Bulls. I have no issue with those breeds, but they aren't known as breeds that do coursing or engage in agility contests. I also don't think there's much of an organized group in Vegas for that sort of thing. I could be wrong.
