In 1976, they got past the penetration barrier by injecting the DNA-containing sections of Rana sperm, called nuclei, into Bufo eggs. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.

This is important because in a half human/half dog situation, both of those orders of turning genes off and on would happen at the same time. Theres not much else to say. You might think that having both of these orders at the same time would be finethat maybe one would win, ending up with either two arms and two legs, or with four legs. And without limbs developing the right way, all development would stop and the developing embryo would die.
