The parents of their different species dont match up. Losing that information would be bad, so species evolved to organize the information into sections called chromosomes. Earlier experiments with mouse and human cells had revealed that immature sperm that still contain two copies of each chromosome could fertilize an egg and produce live births--the egg is evidently able to expel two extra sets of chromosomes before proceeding with normal development. But a 2018 study made scientific waves when it found that men who wore boxers had 17 percent more sperm than men in briefs. The kidneys can fail first reddish urine then shutdown.

Sperm can pass right through the oviduct and end up in a womans interstitial fluid surrounding the internal organs. We wont have any Mogs walking around, because even though human and dog genes are pretty similar, they are regulated in very different ways.
