They are very pretty, but I agree, they aren't really a breed, they are husky mixes (kind of like alaskan huskies).

And since huskies shed a TON they probably do too.

Poodles, some terriers, ect (dogs with hair, not fur) shed very little. Our Shih Tzu mix doesn't shed, and my cousins, who are allergic to dogs, aren't allergic to her. My advice would be to go to the pound, and spend time with each dog to see if your sister has a reaction to him.

Good luck!!!
