The problem with identifying dogs of uncertain, probably mixed, ancestry is that they can be unique. Their litter-mate may not even look like them.
I can't even be certain of the breed(s) of my last four dogs. I had a mostly Irish setter, a mostly black lab and, now, some kind of chocolate lab mix and a dog who could be 100% Plott hound or 0% or anywhere in-between.
It's fun, sometimes, to guess but I'm afraid that some folks expect that dog-lovers can take a look at a few photos and say, "Oh, yeh, that's a Guatemalan Gazehound fer sure!"
BTW, I'm pretty sure that's a Guatemalan Gazehound you've got there.
