I thought maybe momma throw backs but there ain't no way a yellow dog and a white dog are gonna have black puppies.
Why not? With all the breeds in a dogo and who knows whats hiding in a cur dog, they can come out any color. Hell dogos come out long haired sometimes. Black and brindle are both common with dogo crosses.
Anybody else see these colors from a yellow cur and a Dogo?
No brother. It was a traveling salesman plain and simple.

Just cull your losses and move on.
