my dog just rolled in a dead fox. he stinks soooo bad. i dont want to buy something for it so does anybody know a home remedy?? pleeease help!

Our 1-year-old male, (overweight), was outside and came to the house throwing up. Once inside, he was fine. Drank and ate, etc. Later that night he just was not himself. The next day, he became lethargic and felt warm. We took him to emergency. His temperature was 105. He was not eating or drinking. They gave him a water IV, a shot to settle his stomach, and sent him home with us with instructions to watch him and take him to his vet if he does not start eating by day 3 (for fear of fatty liver disease). We did not have anything to force water, so my husband and daughter used a juice box straw during the day. The next day, we took him to our local vet. After $400 in, they did blood work and x-rays. They need to do a liver biopsy ($800) and food IV (no price) to further help him. Our family has not had a good financial summer (husband had brain tumor removed). We stopped at $400 and requested home options to help Gizmo. They offered a home IV and syringe for force feeding. I wished the first emergency would have offered this. We should not have waited until day 3. Vets are so helpful and knowledgeable, but I feel it is a lot about the money; and now unfortunately, we cannot pay the high price. We force feed 3 - 4 times a day. We went from 15 cc per feeding upto 30. He receives 150 - 200 ml water via IV daily. He does not seem to be improving. He throws up at the smell of food. (Treats backfire any improvement.) We have another cat; and it just does not look like Gizmo has had a BM. I have read about trying "pumpkin" from a can and "fish oil" to help with constipation. Any other advice? We are learning this process too late. :confused:
