What breed will appear when Tibetan mastiff breeds with local hounds?

Hybrid varieties, commonly known as strings.

You must define a concept. What is a variety show?

A breed requires stable traits, that is, both parents belong to this breed, and all the characteristics of the born dogs are consistent or in a small range. And after many generations, this requirement has been met, and the number has also reached long-term reproduction. Will be accepted as a new variety.

Instead of giving birth to a dog, it looks different from other dogs and is a breed. His descendants may be more different from themselves, so how can they be called variants?
