My adult daughter has always had allergies to dogs and cats, while getting the yorkies has not triggered an allergic reaction like other dogs she still has some reactions to them sometimes (I don't know why not all the time but only sometimes). I will say though it has not been a big issue and my daughter is still at home while attending college. We have smaller yorkies, one is just over 4lbs and the other just over 2lbs (but is still a puppy and growing). they have been really healthy! I think they are great additions to our family
