How long can a dog go without eating after surgery? - in detail
After undergoing surgery, dogs may experience decreased appetite due to stress, pain, or the effects of anesthesia. The duration for which a dog can go without eating after surgery depends on several factors, including the dog's size, age, overall health, and the type and extent of the surgery.
In general, most dogs can safely fast for up to 24-48 hours after surgery. However, it is crucial to monitor your dog closely during this period. If your dog has not eaten within 48 hours, you should consult your veterinarian, as prolonged fasting can lead to complications such as hypoglycemia and hepatic lipidosis (fatty liver disease).
Smaller dogs and puppies are at a higher risk of developing these complications because they have less body fat reserves to maintain their energy levels. Conversely, larger breeds can often withstand a longer period without food, but this should not exceed 48 hours without veterinary guidance.
It is also important to ensure your dog stays hydrated during the post-operative period. Offer small amounts of water frequently, and if your dog refuses to drink, notify your veterinarian immediately, as dehydration can be serious and may require intravenous fluids.
In some cases, your veterinarian might prescribe a specific diet or recommend hand-feeding to encourage your dog to eat. It is essential to follow your veterinarian's advice closely to ensure your dog's smooth recovery after surgery. If you notice any signs of distress, such as lethargy, vomiting, or abdominal pain, contact your veterinarian promptly for further evaluation and care.
