No, because humans and dogs have different number of chromosomes.A human has 46 Chromosomes. When humans reproduce, 23 chromosomes from a girl+23 from a boy= new human baby with 46 chromosomes. A dog has 78 chromosomes.

This question is absolutely disturbing, what is a girl and a dog doing having sex in the first place???
What is wrong with people in this world, for GOD's sake!
Bestiality (humans having sex with non-human animals) is illegal in pretty much all places now, isn't it?
I sure hope so!
