However, different subspecies of wolves can and do interbreed. This is because they are all part of the same species, *Canis lupus*, and are therefore genetically compatible.
Here are some examples:
* Gray wolves and red wolves can interbreed.
* Gray wolves and eastern wolves can interbreed.
* Gray wolves and coyotes can interbreed, resulting in hybrids known as "coywolf."
So, while wolves don't "get married" in the human sense, different kinds of wolves *can* interbreed and produce fertile offspring.
