Thanks for your ideas everyone! You're all great. We're going to try the ammonia first. The whole trash thing has been a problem for everyone. It makes a mess that my sisters and I have to clean, gets my mother very angry at Daisy, and gets my father very angry at my mother for being mad at Daisy! He just got home from the hospital and when he found out Mom had sent Daisy outside into the snowstorm one day after making a HUGE trash mess, he got very mad My Dad and I love Daisy the most in the family, you see!
