Wolf variations and addition of dogs

I was thinking about adding 2 more wolves, one being from hot biomes, and the other from cold biomes. these wolves would have respective colors, brown or beige and white or perhaps black and white, the wolf from hot biomes would be similar to coyotes, the wolves from cold biomes to the Siberian husk. In addition to wolves, there would also be their domestic variations, dogs, which would only appear in villages like cats, and would be more common in villages in snowy biomes, while in hot biomes like the desert, more cats would appear respectively. dogs, in my head, could have about 6 breeds, just as cats also have different breeds, and they would be different from wolves, because they wouldn't attack, but they could learn tricks and they could play, and I think the emotional value would be equivalent to the usefulness of wolves which would be more useful for combat and companionship for warriors.
