Both Standard Poodles or any type of Poodle are supposed to be non-shed or Hypo-Allergenic!! Ger, Shep. and Husky's all shed like heck too!! I had a Great Dane that shed terrible also. Labredoodles/Goldendoodles you have to go back several generations for them not to shed, That mix might work with your sister's allergies...Good-Luck,
