This is a list of small dog breeds which virtually don't shed any hair. If you own one of these dogs you'll be hard-pressed to find a hair in your home. That's how little they shed!
If you're a clean-freak then one of these dogs may be perfect for you. You never have to vacuum up hair!
The low hair shedding breeds may also be better for you if you have allergies to dander (the dead skin flakes that cause allergies) because it's thought that the low hair shedding breeds below produce less dander than the higher shedding breeds.
(This list is in no particular order -- they are all low shedders)
