How Long Can a Dog Go Without Eating? (11 Quick Facts)


How Long Can a Dog Go Without Eating

It can be a scary realization once you notice it’s been 24-hours and your dog hasn’t touched his bowl of food. If your dog neglects to eat — it can leave you thinking the worst! Thankfully, a dog can go a few days without eating before things become serious.

A healthy dog can live up to five days without eating. With some dogs lasting as long as seven days. If a dog is not drinking, however, this is more of a concern. A dog that is not drinking might only live for two or three days.

When a dog does not eat (or drink) for a prolonged period, the body will use stored fats and protein for energy. And once this is complete, the body will start eating away at muscle — which is exceedingly dangerous for elderly or sick dogs in particular.

How Long Can a Dog Go Without Eating After Surgery?

When a dog has come out of surgery, it’s not uncommon for them to refuse eating or drinking for the first 24 hours. Most dogs can go two to three days without eating or drinking, however, anything longer should consult with a vet.

If your dog is not wanting to eat but is willing to drink, this should be monitored for the first 24 – 48 hours. Anything longer, and you might want to consider your options to reassess the current state (and health) of your pooch.

How Long Can a Dog Go Without Eating When Sick?

It’s common for most dogs who are sick to avoid food. Most sick dogs can go as long as three days without eating or consuming water. Anything longer might be a cause of greater concern. This timespan also depends on the health of your dog.

If your dog is fairly healthy, he/she might live longer than three days. Whereas if your dog is regularly sick or has a poor immune system, it’s likely they’ll be able to withstand the three days. Remember, if you’re concerned about the health of your dog — visit your vet!

How Long Can a Dog Go Without Eating But Drinking Water?

A dog can last up to five days without eating, so long as it’s drinking water. Some healthy dogs can live as long as seven days without eating but drinking water.

All-in-all, the timespan depends entirely on many factors, such as:

  • The age of your dog
  • Breed and gender
  • Current illnesses (e.g, Pancreatitis, Kidney Failure, etc)
  • Overall health and well-being

Older dogs, such as elderly dogs will not be able to last as long as healthier dogs, even when continuing to drink water. The same applies to extremely ill dogs. And this is all due to the immune system of a sick dog vs a healthy dog.

How Long Can a Dog Go Without Eating With Pancreatitis?

A dog with pancreatitis can live up to three days without eating. However, this is only valid if your furry friend is continuing to drink water. Most healthy dogs can last between five to seven days without eating, so long as the water-intake is maintained.

Some veterinarians will recommend your dog to avoid eating for 24-hours, specifically if there has been a recent flare-up regarding pancreatitis. Any longer than two to three days calls for a more serious observation though.

How Long Can a Dog Go Without Eating With Cancer?

Canine cancer is an unfortunate illness that can impact your dog’s ability to consume foods. A dog with cancer can live no more than three days without eating. Most dogs live up to five days without eating, however, for more sick dogs this number decreases significantly.

Much like other sick dogs such as canines suffering from kidney failure or pancreatitis, a dog with cancer should not be force-fed when in extreme pain. Doing so might cause more of a crisis, creating further inflammation or uncontrollable nausea/loose stools.

In this instance, you must monitor your dog’s behavior during these two-days. Otherwise, opt for additional care from your trusted vet if any of the symptoms persist.

How Long Can a Dog With Kidney Failure Go Without Eating?

The average timespan a healthy dog can go without eating is five to seven days. For the more illness-prone dogs, such as dogs with kidney failure, might only live up to two days without eating or drinking.

If your dog with kidney failure is on his way out, the loss of appetite will suddenly come-on. Meaning no matter what foods or liquid you attempt to offer, they’ll refuse. In this instance, it’s important to make the prompt decision to seek medical advice.

How Long Can a Dog With Parvo Go Without Eating?

Canine Parvovirus, or parvo for short, is a fatal illness that can affect a dog’s appetite. Most dogs can go a maximum of five to seven days without food, whereas a dog with parvo might only last two days without eating.

Dealing with a parvo dog that refuses to eat is slightly more difficult, given their condition. Forcing a dog suffering from parvo to eat can cause more pain or inflammation, which as a result will spark worse long-term effects.

If your dog with parvo will not eat or drink anything, start by changing their diet as they might not enjoy the foods being offered. When all else fails, invest in taking your dog to the vet to ensure proper care can be provided.

How Long Can a Diabetic Dog Go Without Eating?

Diabetic dogs require regular insulin to be administered after every meal. If your diabetic dog goes without eating for longer than two days, do not administer insulin. Instead, seek medical advice as to what steps you can take moving forward.

How Long Can an Elderly Dog Live Without Eating?

The older your dog, the less likely it can survive without eating. Elderly dogs in particular might last one to two days, at most, without eating before becoming extremely ill or risking possible fatality.

Although dogs can last a maximum of five to seven days without eating, that’s only if your dog is fairly healthy and continues to drink water. If your elderly dog is unable to do such, then the chances of survival are much lower.

Is it Normal for a Dog to Go a Day Without Eating?

Sometimes it’s common for dogs to go a day or two without eating, which is fairly normal in sick dogs. Most sick dogs will avoid food due to a lack of hunger, or an inability to properly stomach their meals. This can also include water.

What isn’t normal, however, is if your dog goes any longer than a day without eating or drinking anything. This might indicate a more serious problem going on — which might require the involvement of medical attention.

It’s important to monitor your dog’s behavior after going a day without eating, to ensure nothing sinister is going on. You should also do your best to address any additional worries, such as sudden distress or physical pain that might be accompanying the lack of appetite.

How Long is Too Long for a Dog to Go Without Eating?

Food intake is vital for your dog’s health and well-being. If your dog is unable to eat for any longer than two days, it’s best to visit your VET. Waiting any longer than three to four days is far too long for a dog to go without eating.

The longest an average, healthy dog can survive without eating is five to seven days, which is why nipping the problem in the bud can help avoid an unprecedented crisis. If you’re worried about your dog’s ability to digest or eat food, seek medical advice after two days to assess and resolve the situation.
