18. French Bulldog
The French Bulldog is a relatively rare breed that are known to be outstanding companion dogs. They weigh from 15-25 pounds and stand around 11 inches tall. They are known to drool and shed, but are fantastic for apartment living because they are great with small spaces and do not bark loudly. Seniors will adore the French Bulldog because it is a breed that thrives on human contact. They are fairly easy to train and incredibly gentle, even around children. As well, they are intensely loyal and can serve as watch dogs.
