I mean... what happens when you inseminate one with the other? Is it viable?

1. Yes.

If two animals are biologically capable of producing fertile offspring together, they're the same species. Some breeds like bulldogs do have problems giving birth due to physical characteristics, like the size of the skull, and may require Caesarean section. Now, I doubt that a female chihuahua would survive pregnancy with a St. Bernard for such physical reasons (though the inverse would probably be fine). But the eggs could still be fertilized, and if they were allowed to fully develop, perhaps through human intervention, the offspring should be able to breed.

Thus both are canis lupus familiaris, a subspecies of canis lupus, which is better known as the wolf.
