Chihuahuas are intolerable pure. (SoCal has an abundance of them). When mixed, the results are exponentially better.
I sense Bailey has a lot of pluses, other than his intimidating accent. 🙄
My dear departed Henry was, we thought, half Chihuahua and half fox terrier, I saw another dog that could have been his twin and his human knew the parent dogs for sure.
A while before he passed away, I did the DNA on him to find one parent was pure Chihuahua and the other was pure Pomeranian. My vet said if you throw water on a Pomeranian, they become a chihuahua...
Anyway, a neighbor called him Mr. Machito and it fit. He swaggered and ruled the sidewalks on his walks. He sort of didn't know which half of him was more dominant, the chihuahua or the pomeranian! And he was very protective of me to be sure!
But he mostly had a very very sweet cuddly side and I adored him.
