We have a Landseer Newfie mix. She has traditional Landseer markings and webbed paws from birth, the small Newfie brown eyes, some Newfie facial features. We were told she was mixed with a Bernese Mountain Dog, and this is likely; I saw the litter, and several pups had Bernese markings. She is about 7 months old and does not drool, although her jowls are starting to droop a little. Are we in the clear, or do Newfies not start drooling until older?
