Wait, let him cook. This might be the solution to idiots that want wolf dogs. Give them something that is technically a wolf dog, but too tiny to actually hurt anyone.
I have a wolf dog, and she is the sweetest, most loving dog I've ever had! Not an aggressive bone in her body, and she is about 50% pure FLOOF. I love her so much, and she is currently cuddled up on top of my feet as I sit here at my computer desk.
Genetically the cross is theoretically possible. The difference in size of the individuals, especially the reproductive organs creates a barrier that prevents crossing.
If the differences had been created via natural selection not artificial selection, a great Dane and Chihuahua would likely be listed as different species or subspecies for the same reasons.
