 Rocky Mountain spotted fever, that's one that's all over, and that's carried primarily by the American dog tick. So the tick that primarily gets on your dog can carry that. And then there's one that's fairly new, and it's the scariest of all. And it's carried by a tick called the lone star tick. Lone star tick, not from Texas, but the fact that there is a white dot on the back of the female that looks like a little star.
