Poodles are non-moulting and, i think bichon frise? Be careful with crosses, as they may still moult. It would be better for your girlfriend to find out which dogs do and don't affect her first. From experience, i would get the dogs one at a time, train them and see how it goes. Two puppies together are like twins and what one doesn't think of, the other will. They are also more likely to become attached to each other, than to you.
