I hate to well actually you but coyote can breed with dogs and the offspring are known to be fertile for at least 4 generations.

The same is true for wolf-dogs.
There are increased chances for complications so i guess fertility is lower but that is only verified to be true with wild parents specimen.
Domesticated coyote would likely be bred based on properties like ability to coexist with dogs so over time the species would merge more and more, complications would smooth out.
I believe we have a similar history with the neanderthaler.
