Chihuahua
One of the smallest breeds of dogs, Chihuahua makes excellent dogs for seniors. They are very lively and have a lovable personality even if they only weigh 5 pounds. The best thing about owning a Chihuahua is that they are great watchdogs and they require less grooming and minimal exercise. Once they warm up to you, they can become very loyal to their owners but to the point of being aggressive towards other people. They are energetic companions thus making them perfect for seniors who live a fairly active lifestyle.
