Newfoundland’s thick coat requires brushing two to three times a week. Bathe as needed, every one to two months. As pawrents, you still need to brush regularly. Like all dogs with a fluffy coat, Newfoundland gets dirty easily. Expect muddy paws, leaves or burrs stuck in the coat, and stools on the hindquarters. In terms of their teeth, brush at least two or three times a week to remove tartar buildup. Do not forget to also trim their nails once every month or so if your dog doesn't wear them down naturally to prevent painful tears and other problems. Their ears should be checked weekly for redness or a bad odor, which can indicate an infection.
