Millionaire Dog

I read an article a couple of days ago regarding the death of a hotel owner who apparently left her little Maltese dog 12 million dollars in her will! While I can fully understand wanting to set aside some money to be sure your dog is cared for after you are gone, this is ridiculous.
Imagine how much good could have been done if she'd willed even half of that amount to the ASPCA or some other animal welfare organization. Her dog would have still had more than enough set aside for it's care, and countless other animals could have been saved.
What in the world was she thinking?
