There are many reasons your dog might not eat. They can range from simple explanations to serious complications. To complicate matters, just because your dog isnโt eating, doesnโt mean they donโt have an appetite. A dog with a dental or other oral issue, including injury, may not be able to eat but is still hungry.
Other conditions can cause a dog to lose their appetite because they donโt feel well. To avoid making the situation worse, work with your veterinarian for a solution instead of trying to fix it yourself.
What to do depends on a dogโs particular situation. For puppies, not eating is more urgent than for a healthy adult with no other health issues.
Puppies can quickly become dehydrated and/or have low blood sugar, known as hypoglycemia. This is especially true for toy breeds and puppies who are still nursing. If your puppyโs appetite goes down even a little, or if they skip a meal, call your veterinarian that day for what to do.
If your dog is a known picky eater, you can try different dog foods or temporarily offer plain cooked, skinless, boneless chicken breast with white rice. You can also add canned food to their dry food, adding warm water to their food, and cutting back on treats. If you have multiple dogs, try feeding the dog thatโs not eating well separately.
For dogโs who are seniors and are being fed from a bowl on the floor, try raising the height of the bowl to see if thatโs more comfortable for them.
But if an older dog isnโt eating properly, try not to spend a lot of time trying a variety of things like switching to another senior dog food. Older pets are more likely to have medical conditions such as problems with the kidneys not working as well as they should. Some of these concerns may require special dietsโso itโs best they see a veterinarian.
If your dogโs decreased appetite along with other symptoms, call your veterinarian. They can let you know if the situation is safe for you to wait for a scheduled appointment or if itโs a possible emergency. For example, you may have a dog whose breed is more prone to bloat, which is considered a medical emergency.
If youโre scheduled for an appointment thatโs not on the same day, your veterinarian may also let you know what you should and shouldnโt do in the meantime and what to do if your dogโs symptoms, such as in the middle of the night.
If theyโre still drinking water, a healthy adult dog can go about 3-5 days without food but that doesnโt mean you should wait that long before contacting your veterinarian. If your healthy adult dog is still not eating on day 2, call your veterinarian for advice.
A puppy shouldnโt go a whole day without eating. For some, like nursing puppies and small breed puppies, even going several hours beyond their normal meal time can be harmful. Puppies are at an increased risk for low blood sugar, which can cause seizures.
If your adult dog isnโt eating their normal amount but is still in good spirits, active, drinking their usual amount of water, and doesnโt have additional symptoms, you can likely wait 48 hours before having them seen by a veterinarian. But given it can take days to get an appointment on a non-emergency basis, it doesnโt hurt to call your veterinarian for advice.
Call your veterinarian right away if your adult dog has known medical conditions and/or has any additional symptoms such as:
Let your veterinarian know whatโs going on so they can decide if you need an emergency visit or if your pet can wait to be seen.
Whether a puppy is weaned or not, if they arenโt nursing or eating their puppy food like usual, contact your veterinarian the same day, even if there arenโt additional symptoms. Though all puppies are prone to low blood sugar, toy breed puppies are particularly at risk.
