African wild dog
We spent some time living in East Africa back in the day, and actually saw these guys in the wild while on a trip to Zimbabwe. They are very rare and quite spectacular in the wild. The ones we saw had pups. And there were a couple of researchers out trying to dart them. Fun stuff.
I found them tricky to draw though. They don't stay still too much and they have a very odd shape. Not like regular doggy dogs.
Would love to go to Madagascar.
