>>124057644Almost certainly no viable offspring. There's three main categories of failure in animals.
>square peg in round holeIt just doesn't work at all - they're too different for any kind of genetic combination. This is most animals with most other dissimilar animals, where dissimilarity is usually determined by chromosome count and closeness on phylogenetic tree
>It works but doesn't work longThe embryo expects some womb conditions, nutritional state in the mother's body, or chemical balance that it's not getting. It'll last for a little while, a few days to a few weeks, and then when the above issues hit a breaking point the pregnancy dies out and usually self aborts
>It works and it works long but it won't cross the finish lineConditions are working out in the short term, but because of stuff like size differences, hormone effects, nutritional demands, body shape, whatever; something is gonna fuck up in the mother as the fetus matures or when it's time to actually give birth, and probably in a way that kills or will seriously injures the animal in a way that will foul up the child.
My guess is dogs are almost certainly category 1 square peg failures - it's usually based on similar chromosome count to avoid a case 2 or 3, such as in mules (horses have 64, donkeys have 62, and the offspring are 99.99% infertile from it) and ligers (tigers and lions both have 38). Humans only have 23 chromosomes and therefore it's extremely unlikely for them to be able to cross-breed viably with dogs, which have 78.
