Has anyone ever heard of this?

I was hiking one day, and I saw some strange looking beautiful dog, pointy ears like a Doberman, looked like a pitbull with a longer snout...and the coat was greyish blue...I had to stop and ask the owner what kind of dog was it...and she told me it was a Hawaiin Blue Pitbull...Has anyone ever heard of it? If so, can you connect me to some breeders, this is the dog I really want...

I tried googling it in so many ways, and I only get Blue Pitbulls from Hawaii...which is not the same as I saw that day...The lady could be wrong and the dog could be a mix...Geez I'm in love with this dog...
