No, it's really temperament. And you see chihuahuas that are very feisty, and bitey. And you see chihuahuas that love to just be cuddled, and we've had everything from the last class, we had Chihuahuas and we had bullmastiffs. So we had, you know, 150 pound dog and a three pound dog, it just really depends. And we work on the size of the dog to interact. If it's a large dog, it's easy for people to pet from a wheelchair, if it's a tiny dog, it might need to be placed in their lap or on their bed. And so those are things in the class that we teach how to do we put a barrier down so we're not spreading germs and just being conscious of things like that.
