It is very stressful when your dog suddenly refuses to eat. Knowing how long can a dog go without eating will ensure that your friend stays healthy.

In dogs, most of the stored energy comes in the form of glycogen stored in the liver and muscles. So let’s go into the details right here in this blog. Here is what you can identify and do when your dog won’t eat!

How Long Can a Dog Go Without Eating?

Generally, a dog would survive for at least 3 to 5 days without food, but factors like the age and health of the dog greatly influence the extent of survival due to variations in hydration among other aspects. For example, puppies would require more constant feeding while an older-aged dog is usually more frail and likely to suffer major health risks due to skipping.

One major concern would be hydration. In dogs, survival without food is possible for some periods but not without water. The survival time of a dog without water is generally estimated to be about three days depending on the temperature and level of activity of the dog.

Can a dog really survive without food and water for six days?

No, a dog cannot survive without food and water for six days. After 6 days without a reliable food source, our runaway dog was very very skinny and very thankful for his water bowl. I’d never wish this on any animal, but if you are asking the question because your pup ran away, his instincts may be helping him survive.

Why Dogs May Refuse Food?

There are numerous reasons why your dog might refuse food, and understanding these can help you address the issue more effectively.

1. Dental Issues 

Dental problems are much more prevalent in dogs than most dog owners imagine and have a huge influence on their health. Disorders such as gum disease, tooth decay, and breakage cause discomfort and pain. It typically progresses into difficulty eating and loss of appetite. Some other common signs include foul breath, drooling, or pawing at the mouth. Regular checkups, cleanings, and dental-friendly treats or toys can help avoid these issues and maintain health in your dog’s mouth. Treating dental health is pretty important to the overall welfare of your happiness and quality of life.

2. Illness

The most frequent cause of a dog that refuses food is illness. Diseases can be gastrointestinal, infectious, or dental, causing the act of eating painful and uncomfortable. A dog starts to associate food with pain due to discomfort while eating, hence refusing food. Here, you’ll find the best veterinary advice and tips for feeding your sick dog.

3. Stress or Anxiety

High levels of stress and anxiety can impair eating. Your dog can become anxious to the point of avoiding food in response to an environmental change, such as moving into a new house or getting a new pet home, among other lifestyle changes.

4. Picky Eaters

These animals are very choosy as far as food is concerned. It is generally related to the experience of the animal or personal liking in taste or texture. For example, an animal that has been fed any particular brand or kind for an extended period often develops a liking for the same and refuses to have food from any other brand.

5. Medications

Some drugs may also cause decreased appetites in dogs. So, in case your dog is being medicated, never fail to ask your vet whether he or she has seen any instances of decreased appetites as potential side effects of the drugs used.

What to Do If Your Dog Isn’t Eating

If your dog is not eating, you might first look for whether the dog suffers from an illness and is being hydrated. In short, “How long can a dog go without eating?” can be said to be that, basically, it can depend, but basically, if your dog stops eating over 24 hours then seek consultation from a vet or try the following tips…

1. Monitor Your Dog’s Health

Monitor the health of your dog properly. Monitor for other signs, such as vomiting diarrhoea, or changes in behaviour. This is the practical guide to tracking what’s changing and what pattern is being followed. This might come in handy if, at any point, you need to consult a professional about your dog’s health.

Minor health problems that may work themselves quickly are:

  • Minor dental problems
  • Hormonal cycle of unspayed female dogs
  • Minor gastrointestinal distress
  • New medications
  • Recent surgeries
  • Vaccinations

2. Assess the Environment

Evaluate your dog’s environment. Eliminate any source of stressor that makes your dog uncomfortable, for instance, loud noises, a new pet, or changes in routine. Sometimes, even a small change in the feeding place can make a big difference. A quiet and familiar space can help your dog to feel more secure and calm during mealtime.

3. Offer Fresh and Tasty Options

Fresh and tasty food can be one of the greatest motivators for your dog to eat. Introduce different types of food – wet food or homemade – to determine what he prefers. You can add low-sodium broth or some of his favourite treats to make the food more savoury and tasty. Warming it up helps release appetizing aromas that will encourage your pup to eat.

4. Schedule Feeding

Feed at consistent times to help control the hunger of your pet. Feeding at recurring times can give your dog a sense of routine and help prepare for eating. This can become exciting for eating, so ensure that all unconsumed food is removed once a certain time has lapsed to discourage grazing. It should be available only for a certain period.

5. Hydration

If your dog is not eating, ensure that they drink enough. Dehydration in dogs can lead to serious health issues, as it disrupts their bodily functions. Water is the key to their existence, and always provide fresh water. If your dog does not want to drink, you can try offering ice cubes or a teaspoon of low-sodium broth added to their water. Hydration can help maintain energy in your dog while adjusting the eating habits.

When to Consult a Veterinarian

If your dog stops taking food for over 24 hours, consult a veterinarian because failure to feed for such a long period causes various health problems. Moreover, if your dog vomits, is having diarrhoea, or appears lethargic, he or she should immediately be taken to a vet for a proper diagnosis of the ailment. Other behavioural changes that may make one suspect something wrong and take his or her dog to the vet include increased levels of anxiety, hiding their treat, or growling at food. Older dogs, or those with any other health condition, are likely to be affected by anorexia and should visit the veterinarian.

How to Encourage Your Dog to Eat

If you think your dog is not interested in eating, there are some effective ways to persuade them.

1. Add Toppers to Their Food

You can encourage your dog to eat by adding toppers to their food. The toppers may include a variety of items such as Guava, Carrots, Seeds or commercial food toppers. This will increase the flavour and make meals more appealing to your dog. They will be prompted to eat.

2. Create a Calm Feeding Environment

Another equally important thing would be creating peaceful surroundings to feed. Feed the dog in a quiet, distraction-free place. Your dog can be more relaxed and even enjoy their feed if there is a tranquil atmosphere around them.

3. Change the Feeding Routine

Another approach is the modification of the feeding routine. One big meal per day should be substituted by multiple smaller meals throughout the day. This may increase their appetite and also help decrease the pressure that they might have when eating.

4. Try various types of food

Dogs at times may not eat as they get bored with their diets. Introduce different flavours and textures to renew the interest in eating. Maybe your dog prefers wet food, freeze-dried, or homemade.

5. Positive Reinforcement

Encourage your dog by giving some positive reinforcements. Reward him with either praise or a small reward whenever he displays interest in his food. Then, his meal would go well into his head because of association, hence will encourage eating willingly.

6. Ensure Fresh Water Availability

Make sure water is always available for your dog. Sometimes, even hydration will depress an animal’s appetite. Encourage hydration by keeping his water bowl filled and clean; hydration itself can improve his appetite.

Nutritional Needs

It is important to understand a dog’s nutritional needs. Here is a general list of nutrients that will add up to a balanced diet for dogs.

Nutrient Recommended Daily Intake (per 10 kg body weight)
Protein 25-30 grams
Fat 10-15 grams
Carbohydrate 50-60 grams
Fibre 5-10 grams
Water 50-100 ml (depending on activity level)

Proteins are needed to keep muscles and bodies healthy, Some of the good sources include chicken, beef, shrimp, and eggs. Fats are also used as they contain essential fatty acids for proper skin health and energy. Carbohydrates give primary energy. The intake of fibre aids digestion, and water helps in hydrating the body along with performing all its other functions.

What To Remember

Every dog owner needs to know how long can a dog go without eating and why the dog refuses to eat. Being proactive and vigilant will ensure that your dog lives a healthy life. When you have nagging doubts, do not be afraid to visit your vet. This is what truly sets him or her apart as it pertains to taking care of your pet’s appetite.

Moreover, a stress-free mealtime experience matters much in the matter of how willing your dog is to eat. This is because every dog behaves differently, and you could take time to know them well enough to understand your furry friend. Patience and attention will encourage great eating habits that will care for your dog’s complete well-being.
