Well, some kinds of dogs are like that. [Says the guy from the world of ridiculously tiny toy dogs that have been bred to within an inch of their life.]

I think there are dogs that are similarly sized to wolves? Or a few that are bigger, though I don't think I've seen any of those ones here. I don't think I've seen any lion dogs, though. That sounds like it'd be something bigger, if it had lion anything in it - the things we called lion dogs in my world were kinda huge, but we only ever had statues of them.
