It can happen.<quoted text>
You did not answer my point: have you **ever** heard of a chihuahua and a wolf cross-breeding? No?
Your point is invalid.
A chichuachua is just a sub species of a dog
In a same way pigmy people cameroon are a type of human .
The only way an animal or human can produce a fertile offspring is if they are the same kind.
Lion and a tiger produces a liger but the lige is infertile.
A house cat and a serbal can produce a savanah because they are of the same kind.
A chi chua chua is a product of humans mating different species of dogs to get their desired look.
The majoroty of dog species are man made.
If theybwaned a wolf and a chichuachuanto mate they could make it happen.
