wow she is Adorable and she does have some newf looks, that white patch on her chest is very newf looking but whoever said about her head looking delicate is right, she doesn't have the newf head and I've seen some newf mixes that have white paws or white ticking on their paws. does she have dewclaws?

I picked up my purebred newf at 8 weeks and she was 16 lbs
my newf/pyr was 14 lbs at 9 weeks
they now weigh 120 and 111, both are females

You've got a wonderful pup there - Congrats!
