I posted a question on sept 21. First I want to thank everyone that answered it and showed compassion. It's interesting that most of the answers I got suggested bone cancer, and possibly old age. The bone cancer is the most intriguing. I had just lost another female 12 year old golden just a month before from bone cancer. So i lost 2 dogs in 6 weeks. I knew it wasn't arthritis, because it came on suddenly, especially in the last few days. She went from being able to limp on one leg to loosing strength in both legs in a couple of days. I'm not doing an autopsy, because I don't need to feel less inadequate than I already feel. I want to start a fund for people that are on low incomes, to be able to receive adequate care for their pets. If anyone has any suggestions on how to achieve this, it would be greatly appreciated
