Brownie get the veterinary Care he needs

Hello, my name is Tiffany and this is Brownie, my 16-year-old son's emotional support dog. Brownie's having some health issues. He has been vomiting and having very bloody stools. We took him to the vet once already, and he was doing okay for a little bit. It has started over again, and now we are struggling with finances to be able to bring him back to the vet. This is why we are trying to raise money so that we can take him back to the vet to get more tests done, x-rays, and medications. Any donations are greatly appreciated. This is our last resort. If we cannot raise the money, I will have to unfortunately surrender him.
