All dogs can interact well with children, especially if they're introduced as puppies to a home where children are already underfoot, says pet expert Marc Morrone. Still, many breeds have proven over the years to be particularly gentle and accepting of children in the household. To create this list, we turned to the World Atlas of Dog Breeds, 6th Edition, which rates breeds for their compatibility with children. Remember, however, that no matter the breed, be sure to monitor the first interactions between your children and any new pet. It's easy to see why the beagle is one of the most popular dogs in the United States. It's a happy-go-lucky, friendly breed and makes a wonderful family pet.
