After identifying and correcting (or treating) the underlying cause of the anorexia, the veterinarian will work towards establishing a healthy, well-balanced diet for your dog. This includes increasing the fat or protein content of the food, improving the taste of the diet by adding flavored toppings and broths, and, occasionally, heating the food to body temperature.
Intravenous (IV) feeding may be required if the dog is severely anorexic, especially if it has not eaten for three to five days or longer. Also, if the anorexia is due to pain, your veterinarian might prescribe pain medications for your dog.
Anorexia is a serious condition which requires you to monitor and watch your dog very carefully. It is important you notify the veterinarian of any progress (or lack thereof). If your dog does not start eating on its own after a day or two, you will need to take it back to the veterinarian for more treatment options.
