I would get a large syringe, try tractor supply and get something liquid up her. I like to use clay or Colloidal Silver . Up the pumpkin too.
My daughters had a rabbit with a growth and took it to the vet. he said it was a tumor and to tie it and it would fall off. They did this and it took about one month to fall off. It came back the very next day. So then they put some clay on it and it went away immediately and never came back. So I am thinking clay everyday for your dog in her food. Do a search on this, they have used it in animals food for many many years, it is very healing.
I would love to hear how it turns out for you. I am a holistic dog breeder, with a website, and while I do have a stools page that talks about clay, I am making a clay page, so would love to share some good stories.
