Hitler and his many fallacies

Now as we all know, hitler was a insane man, well on top of all the horrible things he's done, he can't even make a valid argument. In chapter 11 of his book, hitler says that different races shouldnt breed with each other because, "its just wrong", considering that in the animal kingdom different species of animals don't breed with. Well there are at least two things completely wrong with this statement. First of all, there are no sub species of humans, we are all the same. A race is not a species. It's equivalent to different dog breeds, if a husky and a labrador have puppies then you have husky/lab mix puppies and there is nothing wrong with that. Also, different species do breed with each other on rare occasions (i.e liger, cama)
