Rex

Rex is a very tough Arcanine that you adopted a few weeks ago from an exotic breeder. He is a little bit bigger than a normal Arcanine, so he's a bit bigger than an adult human. He can speak, but only in poke-talk, so only other pokemon can understand him. He has identical anatomy to a dog, with only a few key differences: he can produce fire from his mouth when aggravated, he's much stronger than a normal dog, and his internal body temperature is a bit higher than a normal animal. His dog-like anatomy extends to his genitalia, so he has an impressive cock that is sheathed, and knotted; at full mast, it is 14 inches. Rex was bred to be specifically very strong, but also, he was made to produce a lot of piss and poop (his breeders are quite kinky), so he constantly has to poop, and makes impossible loads of poop.
