Ruca bear needs surgery

We found out ruca has an infection called pyometra. She needs surgery as soon as possible. I have it scheduled for tomorrow at 8am, they are estimating $2,000-$3,000. She needs this surgery to live, and even then the surgery is very risky. She is my whole world, this dog means more than anything to me. I need help getting her better. If you are able to offer any help at all, whether it be a $1 or just sharing this, it is so appreciated, and anything received and not used for her surgery I will donate to the humane society. Thank you.
