Hello Doghealer,
Here are some pictures of Sapphire for further reference. The first two were taken at roughly 9 weeks, and the other two were taken at 3 months (about 13 weeks).
Your little girl might have some Kuvasz blood, but I don't really see it. However, I wouldn't know for two reasons: 1, my family is new to Kuvaszok, and, 2, one never can tell how a mix will turn out.
Do Irish Wolfhounds have dark pigment? I think Great Pyrs have some dark pigment on them, like Kuvaszok, but maybe not as much. I don't know much about dog breeds.
Still, I wouldn't worry too much about breed. Some animals do not have the typical breed temperament anyway, and in cases like this, where the dog's breeding is unknown, there is no way to really know what breeds (if any) your girl was mixed with.
