I'm sorry that you are financially unable to do the recommended testing and treatment for your dog. If the dog does in fact have a liver shunt, surgery is usually the recommended treatment. Treating the dog with lactulose and cans of L/D will only be a temporary band-aid. There are dogs with internal shunts that are not surgically correctable, and those dogs are usually put on diet and medications. You might want to see if you can finance the diagnostics and treatment with care credit or something else. In the event you cannot take care of the dog, consider giving it to a reputable rescue who will take on the responsibility of getting it treated. Best wishes, I'm sorry you and the dog have to go through this.
