Some popular small house dog breeds in the United States include the beagle, Yorkshire terrier, French bulldog, and dachshund. According to the American Kennel Club's list of "Most Popular Dog Breeds in America," these breeds rank among the 11 most popular as of 2015.
Beagles are considered great small house dogs for a few reasons. Their friendliness towards other dogs, strangers and people (including children) make them excellent family dogs. Animal Planet also says beagles are easy to train and are low maintenance in regards to grooming, but they do benefit from daily moderate exercise.
Yorkshire terriers, or "Yorkies," are often popular with people who enjoy very small breeds, as they are only 4 to 6 pounds when full-grown. Yorkies are very playful but need minimal exercise, so they are good apartment dogs. However, Dog Time also cautions Yorkie owners to keep this breed away from infants and small children. They do better with older children who understand how to properly interact with a family dog.
French bulldogs are wonderful small house dogs for individuals or families who are not incredibly active. According to the American Kennel Club, this breed is not athletic and does not need much exercise to be content. Like the beagle, a French bulldog requires little grooming to maintain its coat. They do not do well in heat, but a house equipped with air conditioning in warmer climates is accommodating.
Although small in size, miniature dachshunds have a lot of energy, so adequate daily exercise is a must. They love spending time with their human families and are great watch dogs because of their protective qualities. Unfortunately, it is common for this breed to develop back and spinal cord problems because of their long bodies, as PetMD points out.
