Nether Wolf

Nether wolf type. Their skin resembles a magma cube— dark colored with pulsing veins throughout— and come in two variants. One variant is regular magma color with orange eyes, while the other would be a soul fire variant with blue eyes and glowing blue veins. They could spawn in nether wastes/soul valleys (or perhaps in crimson/warped forests.) They can only be tamed with wither skeleton bones and heal off of cooked meat. They inflict fire damage on enemies and can swim in lava.
