Sorry for this pic not being a drawing, I suck actual balls at using MS paint.

UKRAINIAN THERMAL SHEPARD

Looks about the same as a G.S.D, just a bit fluffier.
Very dense despite being G.S.D sized, he weighs like 250 pounds.
>Glows a faint green
Much higher body temp than a normal dog, his baseline body temp is 150F.
He will continue to grow hotter and hotter until he is about as hot as a raging campfire. You can use him to heat your house or cook your food.
Heat can be controlled by feeding him chunks of graphite, which will lower his body temperature.
Likes to lie on top of you.
You swear you get a little nauseous around him, but you don't really know why...
