that could VERY easily be a pure bred standard poodle with a natural face...
or either a lab x poodle or a golden x poodle, PLEASE do not buy either of these "breeds" form a breeder, currently there are VERY few "responsible" "doodle" breeders, and plenty of "labradoodles and goldendoodles" in shelters (mostly because the vast majority of them do shed and cause isues with allergies despite being told they are "hypoalergenic like poodles" )
it could also be a wheaton, but i doubt it.
hes a very cute larger shaggy dog...
