I must say you picked the perfect pet for your Grandmother. We are both retired and we have two Schnauzers. Miss Daisy is black and 2 and Dom Perignon is salt and pepper and also 2. They are a joy to us, every morning we have our coffee and enjoy their playing time. We have taught them to sit up, shake hands and lay down, then reward them with a "people cracker" They are our constant companions, traveling on vacation, or go with us to do errands like banking, store etc. The bonus is that they don't shed which is great, and they are the most lovable companions one could want.
