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.
Dogs would be a good example for ring species, which show the outer limits of the species definition, if they they occurred in the wild in their many diverse forms. But since they are not, I’d group them as one species still, as their origin is artificial and so are, at least partly, their means of reproduction.
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.
Bio nerd lemmings, could a Chihuahua impregnate a grey wolf and have puppies?
In theory: yes, most likely. In practice? No.

Only with the aid of a step ladder and a lot of determination.
The old school way probably not. By way of humans doing artificially probably.
