You have gotten a lot of great advice from many already. You are so sweet to be so kind to her. She really needs the support!
A few months ago, our neighbors lost their 12 year old dog, a mother, and their new house flooded.
We felt so bad for them....so besides telling them how bad we felt, we went to Costco and bought them a gift basket. Placed it on their porch with a card as well. They found it when they got home. (very suprised!)
Later they mailed us a card that said: "Thank you so much for the wonderful basket of goodies. And thanks, for advice on the water problem. We're lucky to have neighbors like you!"
