Pretty Shocked - Short Hair GP?!

My family and I adopted this good-boy recently. We anticipated his DNA to come back 50/50 Great Pyrenees and Lab mix. However, we got the results today (Embark) and Rufus is 100% Great Pyrenees! The white coat and double dewclaws were good indicators. However, the short hair and look of his mom made this a bit of a curve ball. Either way, we are very excited about our newest family member (he is about 12 weeks old now). Photos of his mother and siblings attached too.
