Cocker Spaniel
Another Spaniel is the Cocker Spaniel. It has the perfect temperament for seniors. You need to groom them a bit, but their loveable personalities and ability to live in an apartment will make it all so worth it.
Scottish Terrier
If you want a dog that needs a moderate amount of exercise to keep you active, a Scottish Terrier will be perfect for you. It needs regular walks, not excessive running. This breed adjusts well to apartment living, is normally quiet, and has a loud bark rather than a yap. It also has an affectionate personality and will be a faithful guard dog.
