I had to look them up as I had never heard of them. Dennis, what do you plan on using them for in AZ? Previous poster (Sycamore maybe?) inquired as to "lion dogs?"
They sure look like a cool breed. I sent my wife a link to one of the breeder pages and told her I want a gunmetal one!
You sure have a bit of work in front of you bringin' up three!
Good luck,
geno
