I have an eight-month old coated Xoloitzcuintli. We've been together for a little less than two weeks and so far he's great. Sadly, most breeders here kill the coated pups because they have no sale value. I got mine for free from a breeder who doesn't kill them but he'd had Diego for eight-months before I took him.
So far, I like his personality characteristics and we fit together well. We did have problems with separation anxiety but he's much better. He lived with Mom and Dad his whole life and moving in with me was traumatic.
Nice dog. Oh, this one is great with kids. I don't have little kids but I meet many on the street and he's been friendly and patient.
