Greyhound
As the largest dog on the list, the Greyhound is also the most sluggish. Retired racing Greyhounds are ideal for elders since they are essentially couch potatoes. If you adopt one from the track, they will be highly socialized as well.
Bichon Frise
The tiny and fluffy Bichon Frise is a cheerful and loving dog that will make an excellent companion. A Bichon Frise weighs between 7 and 12 pounds on average, making it very simple to handle for most people. They’re also very simple to train. They will need to be groomed now and again, but they are generally low-maintenance. A modest quantity of daily activity is usually enough to keep them healthy and happy as long as they have your company.
