Dogs are one of the most lovable and loyal animals on earth, but how long can a dog go without water and food? This is a question that many people ask themselves when they think about how to do proper care for their new pets. You need to know some things before getting into how long your dog can last without these necessities.

A dog can go for some days without water and food. A healthy adult will typically last between 3 to 5 days without sustenance, while smaller dogs can survive 5-7 days.

Younger or weaker animals may not stay without water and food for as long. However, how active the dog is at that time will determine how long it can survive.

If your dog is ill and has refused to drink clean water for more than a day, it’s essential that you seek help right away. Most likely, your vet will give them IV fluids in addition to diagnosing and treating the illness.

Dogs can typically survive approximately 2-3 days without water. But just because they might survive doesn’t mean it’s something they should be subjected to when dehydrated; their vital internal organs failure, that could potentially lead to death.

If dogs are sick, have not drunk any water past one day, go see vets, most likely get iv fluid while being diagnosed. As dehydration can lead to vital organs damage so don’t take it lightely.

How long can a dog go without water And Food before dehydrating?

On a hot day, even just one hour without water can be severe for your dog. On an average they require at least one ounce of water for every pound of body weight per day. However in some cases some dogs may not need to drink anything for up to four days, this is rare, and they will likely already have feeble health by that point due to the lack of hydration.

how long can a dog go without water and food


If your dog’s water bowl appears dry and there is little to no activity from them, it could be a sign of dehydration. If this does happen, keep an eye out for these symptoms, that you should visit the vet.

Dry gums or cracked tongue

Dry gums or cracked tongue is a sign that your pet might be dehydrated. You should always check the color of their tongue when you see this symptom, as it will tell you if they are getting enough water in them.

You will probably notice a dark pink color or even blue tongue if your dog is dehydrated. This color will be light pink with no water around it if they don’t drink enough water. In addition to this, a white tongue may also indicate vomiting or diarrhea.

If the gums are also dry, it means that they haven’t had enough water intake for a very long time. They can survive without food or with a lack of appetite for a few days but will only stay for hours without water per day.

If your dog’s gums are dry, there is no time to waste, and you need to take them to the vet immediately. You should also contact your local emergency center so they can treat your pet as soon as possible.

Dry gums or cracked tongues can also signify other health issues, so you need to take your dog for a veterinary care examination.

Excessive panting

Excessive panting is another sign that your dog might be dehydrated. If they are not getting enough water, it will also make them more tired and lethargic.

If you notice that your dog is panting excessively, it’s best to check their cup of water just in case they are thirsty or find a way for them to drink some more if needed.

The problem could be due to the weather being too hot or from excessive activity. Still, whatever the potential reasons may be, it’s crucial to find a way for your pet to drink more.

Notice that the panting is not just caused by being too hot. It could be a sign of other health issues, and they might need medical attention immediately. It will also tell you if their stomach has been empty for far too long.

Loss of appetite

Loss of appetite is another sign that your dog might be dehydrated. If they are not drinking enough cups of water, it will also make them more tired and lethargic, slowing their metabolism significantly.

If you notice that your pet isn’t eating for a few days in a row, the chances are high that they aren’t getting enough daily water intake. It’s best to take them for an examination as soon as possible, especially if they are lethargic or have other symptoms of dehydration.

Reduced appetite can also mean that your furry friend is sick with a different illness, and it’s important to find out what is wrong before it gets worse.

If you notice that your pet has any of these symptoms, it’s best to take them for an examination as soon as possible and stay by their side until they feel better or have been diagnosed with the problem.

Injury or Illness

If your pet has an injury or they are ill, it is even more important for you to take them to the vet as soon as possible. They need enough ounces of water per pound of their body weight and food just like anyone else, but if their body isn’t working properly due to dehydration, it might not be able to absorb anything that gets into their stomach either.

If your pet is injured or sick, they need to rest and not exert too much energy. Severity of dehydration won’t make the injury or illness better, but it can cause further complications if you don’t tend to the issue immediately.

Sometimes injuries happen without any apparent signs of trauma. Hence, if your dog is acting strange or has stopped playing, it’s best to take them for an examination anyway.

Dark Yellow Pee, or Very Little Pee

Dogs that lack water consumption in their body may also have dark yellow pee. This is a sign of dehydration, which can occur if your dog doesn’t get enough to drink or isn’t drinking but still urinating regularly (like at the same time every day).

If you notice this and think it could be because they’re dehydrated, make sure to call the vet immediately. Since there are other health concerns associated with darker urine, like diabetes and liver problems.

Depleted Skin Elasticity

If your dog is dehydrated, you will notice that its skin will have poor elasticity. It’s important to keep the skin moisturized and hydrated to avoid any issues with the skin.

If you notice your pet’s skin becoming dry or start scratching themselves too much, it will be a good idea for you to take them to the vet as soon as possible to find out what is causing this problem.


Lack of Access to Water

If your dog is in the wild, it might not have access to tap water. It’s important that you monitor their activity and make sure that they can drink enough if it’s hot out or there is no drinking source nearby.

Tainted Water

Your dog might be drinking tainted water if they have been out for a long time without you being there to keep an eye on them. If their water content is coming from a stream or some other natural source, it needs to be thoroughly checked before your pet drinks any of it.

If the water looks dirty or tastes strange in any way, make sure you boil it first before giving it to your pet. This way, any bacteria or chemicals that might have gotten into the water will be killed and won’t make them sick.

Water bowls left out in the sun can also become contaminated. Even if a lid covers them, there is still no guarantee that animals don’t get into the water and contaminate it.

If you have a dog outside for most of the day, it’s best to check their bowl regularly or get a drinker instead. This way, they will have access to fresh water whenever they need it without relying on what might be in their drinking source.

Cold Weather Condition

If it is winter and the temperature falls below zero, your dog might need additional water during winter. Warm water in these days will also help him to warm them up from within so they don’t get too cold and achieve normal body temperature in the first place.

It doesn’t matter whether you have a small or a large breed – all dogs in extreme weathers are at a high risk of dehydration if their needs aren’t met.

It’s important that you regularly monitor their drinking and eating habits, especially if they need to lose weight or haven’t been feeling well for a while.

If your pet seems lethargic and doesn’t eat much at all, it might be the sign of something more severe than just a canine dehydration, so make sure you get them checked out as soon as possible.

Being in an Unfamiliar or Unknown Place

If you travel a lot with your pet, it might be hard for them to get their usual water and food sources. If they are in an unfamiliar place or if there is no one around who can give you directions on where the closest source of drinking water is, make sure that both of these things will not become a problem when going out with your dog.

It is a good idea to check out the area before going on a long walk with your pet so you can figure out where there might be sources of water around if needed and avoid being caught in an unfamiliar place without food or water for them.

If you have been camping recently, make sure that they have access to fresh drinking water at all times. If it doesn’t look clean, bring your water with you, so they don’t have to either face prolonged water deficiency or drink from the same source as everyone else in the campground, even if other animals are around.

Hunger Strikes

Some dogs will refuse food when they want attention or feel anxious about something in their environment. If pet owners notice that they have stopped eating for more than 24 hours, it’s important and its their duty to take them to a veterinarian as soon as possible.

Some dogs will even go on hunger strikes if there is something wrong with their food and the smell or taste of it makes them feel sick. If this happens, try changing their diet slightly to stick to it even when they are sick.

When you go on a long trip with your dog, ensure that you have everything well organized and ready before leaving the house. Knowing where all of their types of food and water sources will be makes them feel more secure, especially if this isn’t something they get to do often.

How to Prevent Dehydration in Dogs

There are a few things you can do to prevent your canine companion from becoming dehydrated and reduce the possible health concern.

Ensure they always have access to fresh drinking water from time and remember not to leave their bowl out in the sun or uncovered when it’s empty.

If your pet has the potential to be exposed to toxic chemicals, make sure that you keep all of those products out of reach, as well as any medications they may require.

If you have a fountain or a water dispenser at home, that can work just fine for pets who don’t drink enough every day.

If you notice that they are not eating much and seem very tired even after sleeping all night long, it might signify that something is wrong with them. Bring them to a veterinarian as soon as possible and make an appointment if you can’t see the problem right away.

If they seem nauseous or have diarrhea, it might be because their body isn’t getting enough liters of water after all, which means there must be something wrong. Talk to your veterinarian about what might be causing this and how they can help you with the problem.

If it is very hot outside, make sure to keep them hydrated even if they don’t seem to want anything to drink at all when traveling or taking your pet on a walk; keep in mind that fresh cool water is best for them.

Make sure to keep their water bowl clean and give it a good scrub every once in a while, so they aren’t drinking dirty water all of the time.

If you notice that something has happened to your pet, don’t wait for too long before taking them out on an emergency trip to see if everything is OK or not.

Keep water bottles with you while traveling or going on a long walk so that your pet can have something to drink when they are thirsty. This is especially important if it’s very hot weather outside and there might not be any other sources of fresh drinking water around for them at all.

These days, more people prefer buying their pets bottled water instead of using the same source for everyone in their family.

This is a great way to ensure that your pet gets clean drinking water all of the time, and it’s usually cheaper than buying bottled water just for them when you buy in bulk.

How long can a dog go without eating?

This depends on the type of food they eat every day, but most dogs will be OK for about 24 hours. A rough estimation is that a dog will go around anywhere between 5 to 7 days without eating.

Why won’t my dog eat anything?

There are many reasons why your pet might not feel like eating anything. Some of them I will discuss in detail.

Food quality

First things first, make sure that there isn’t anything wrong with their food and the smell or taste of it is OK for them. If something has happened to their bowl (it got broken or spilled over), try changing up how you store their food.

If you have just come back from a trip and your pet hasn’t had the chance to eat anything yet, make sure they are hungry before giving them some food.

Sometimes it can be hard for pets to understand what is going on when there is nothing familiar about this situation, so try feeding them small amounts of food during this time.

Health Issues.

If your pet is sick or has digestive problems, they might not feel like eating even if food bowls smells and tastes completely fine to them. If there are any health issues involved with this situation, you need to bring them out on an emergency trip so that the veterinarian can help them get back on track again.

Picky Eating.

This is a very common problem with pets, especially dogs who are used to eating the same food every single day. Try finding a new pet food for your pet and combine them together so that they have more options available to choose from when it comes time for their meal.

Changes in Lifestyle.

If your pet is used to going out on a walk every day and you have stopped doing this for some common reasons or a specific reason in particular there might be a problem with them not getting enough exercise. Try taking them out more often or finding chances to get their daily dose of activity from other sources besides just the walks you take together.

Upset stomach

If your pet is experiencing diarrhea or vomiting, they will most likely not feel like eating anything. Ensure that their canned food isn’t expired. If there is any health underlying issue involved, take it out on an emergency trip to the veterinarian.


If your pet is in a depressive state, they might not feel like eating anything because nothing is interesting going on in their life. Take them out more often, play with them and make sure you give them enough mental stimulation while trying to get their energy level back up again.

It’s important that you take them out more often so that they can have their daily dose of exercise, and if they are really old, then their food intake might need to be changed up a little bit as well.


If your pet is experiencing a panic attack of some sort, then they might not want to eat anything at all. Try figuring out what is causing this behavior and let them know that everything is all right again.

Whenever you move to a new house or change your lifestyle, your pet might suddenly become anxious because nothing is familiar anymore. Take them out more often to explore what is going on in their new surroundings and try to give them mental stimulation by playing with them.

If your pet is experiencing separation anxiety, they might not feel like eating anything at all because of the overwhelming feeling that something terrible is about to happen when you are away from home.

Try giving them time alone so that they can get used to being alone for a little while.

If your pet is experiencing panic attacks, they might not feel like eating anything because there was nothing familiar about this situation at all. So try feeding them small amounts of salty foods when you return from these trips and give them space to process what just happened in their lives.
