Why Is My Dogs Stomach So Warm?

Why Do Dogs Have Warm Stomachs?

When we talk about dogs having warm stomachs, we are usually referring to a dog that has eaten recently.

This is because when dogs eat, they produce gastric juices that help break down the food.

This is one reason that dogs can get sick more easily than humans.

They also tend to vomit up anything they ingest.

As soon as they do this, their stomach starts heating up.

When their stomach heats up, it can cause them to feel hot or even nauseous.

If your dog has an upset stomach, make sure to take them to the vet immediately.

A dog’s stomach can become very inflamed if not properly cared for.

You should never give any type of medication without first consulting your vet, especially if you are unsure of what kind of medicine may be needed.

However, there are some instances where a dog’s stomach can heat up naturally.

There are several things that can cause this, including certain diseases and conditions.

In these cases, the dog will need to see a vet as soon as possible.

Dogs That Eat Too Much

One common condition that causes a dog’s stomach to heat up is when they eat too much.

This is especially true of large breeds like Great Danes and Mastiffs.

These animals can overeat and still maintain a healthy weight.

However, they often experience gastrointestinal problems as a result.

A dog that eats too much may have trouble digesting the food.

This can lead to bloating and other digestive issues.

Additionally, excess fat in the stomach can cause it to heat up and expand.

This can cause nausea and other symptoms.

A dog that is overweight but maintains a normal eating pattern may also experience stomach discomfort.

This is due to the extra strain on their organs and muscles caused by the extra weight.

If the dog’s stomach is swollen, it may be difficult for them to move around comfortably.

They may also feel weak, tired, or lethargic.

Another way that a dog’s stomach can heat up is through exercise.

If a dog engages in strenuous activity, such as running, swimming, or playing sports, their stomach can heat up and swell.

This can cause nausea and vomiting.

The Function of a Dog’s Stomach

Dogs are carnivores; that means they eat meat.

This is what makes them so special in the world of animals.

If you take a look at a dog’s digestive system, it will consist of two parts – the esophagus and the stomach.

The esophagus is where food goes before it gets into the stomach.

The food travels down this tube from the mouth until it reaches the stomach.

Once it reaches the stomach, it begins to break down.

This breakdown of food happens in the stomach.

A dog has four different types of cells in its stomach lining.

These four types of cells help in breaking down the food.

This process of digestion is very important for a dog.

It helps release nutrients and energy from the food for the dog to use as fuel.

In fact, dogs need to eat every three hours to keep themselves healthy and functioning properly.

A dog’s stomach also contains two glands that allow it to secrete acids.

These acids protect the stomach from any foreign objects such as bugs and other bacteria.

They also help to break down the food more effectively.

It should be noted that dogs do not sweat much like humans do.

As a result, their bodies don’t lose heat through their skin.

Instead, their bodies rely on the blood running through their veins to cool them off.

This is why a dog’s temperature can vary from room temperature.

If a dog’s temperature is higher than normal, then there is something wrong.

So, how does all this relate back to the topic at hand?

Well, if a dog’s stomach is warm, then there must be a reason behind it.

And that reason is probably related to the function of a dog’s stomach.

On the next page, we’ll learn about the function of a dog’s stomach.

Why Is My Dogs Stomach So Warm

The Anatomy of a Dog’s Stomach

A dog’s stomach is located in its chest cavity, which is divided into two sections.

  • Cardiac Cavity: This is where the heart is found.
  • Thoracic Cavity: This is where the lungs are found.

The stomach is made up of four main parts: esophagus, stomach, small intestine, and large intestine.


The esophagus is a long tube that runs from the throat to the stomach.

The esophagus has three important functions:

  • It transports food from the mouth to the stomach.
  • It mixes saliva with swallowed food so that it can easily pass through the digestive tract.
  • It stores water so that the dog does not need to drink as often.

Most dogs do not eat much, but if they do, they usually swallow some water with the food.

However, if a dog eats too much food at one time or drinks too much water, then it will have to go to the bathroom more frequently than usual.

In this case, the dog may experience belching or vomiting.


The stomach is divided into two areas by a thin layer of tissue called the serosa.

The stomach is divided into four quadrants: cranial (front), caudal (back), dorsal (top), and ventral (bottom).

The stomach is responsible for breaking down the food and absorbing the nutrients.

The stomach secretes hydrochloric acid from cells lining the gastric glands.

Hydrochloric acid helps break down the proteins, fats, carbohydrates, and minerals in the food.

It also activates enzymes that help the food to become digested.

Small Intestine

The small intestine is the most important part of the digestive system.

It serves as an absorption site for the nutrients that were broken down by the stomach.

The small intestine is about 10 feet in length and is made up of a muscular wall and a mucous membrane that covers its outside surface.

Inside the small intestine there are many folds that increase the surface area of the intestine.

These folds are necessary for the efficient absorption of nutrients from the food.

The small intestine also produces bile to aid digestion.

Large Intestine

The large intestine is about 5 feet long and is made up of a muscular wall and a mucous membrane that covers its outer surface.

Like the small intestine, the large intestine contains many folds that increase the surface area of the intestine.

These folds are necessary for the efficient transport of feces from the bowel to the anus.

Factors That Affect a Dog’s Stomach Temperature

When a dog’s stomach temperature is elevated, it can indicate that there are several factors at play.

Food Residue

The dog may be experiencing vomiting or diarrhea, which can result in an increase in stomach temperature.

As the digestive tract breaks down the food, bacteria present in the intestines will also break down the food, releasing toxins into the bloodstream, which can cause an elevation in the dogs stomach temperature.


Diarrhea causes bacteria to multiply within the intestines, increasing the amount of toxins released into the bloodstream.

This can lead to a rise in temperature as well.

Gastric Ulcer/Stress-induced Hyperthermia

Gastric ulcers can occur as a result of stress or overuse of pain medication.

When bacteria infect the ulcers, they release toxins into the bloodstream, causing an increase in temperature.

Heat Stroke

Heat stroke occurs when a dog’s internal temperatures rise to dangerous levels.

Heat stroke can happen if the heat index rises above 102 degrees Fahrenheit (38.9 degrees Celsius).

The dog’s skin may become red or flushed, it may pant excessively, and its eyes may be bulging or bloodshot.

Other symptoms include seizures, collapse, and unconsciousness.

Heat stroke is not usually fatal unless left untreated for too long.

Vomiting and Diarrhea

Vomiting and diarrhea can both cause an increase in temperature due to the presence of bacteria and toxins in the bloodstream.

How to Check Your Dog’s Stomach Temperature

A good way to check your dog’s stomach temperature is by using a rectal thermometer.

These handy devices allow you to take the temperature from inside your dog’s anus, rather than having to stick your hand up his butt!

If your dog has a history of vomiting or diarrhea, however, then it’s probably best to get him to the vet first to check things out.

He may need fluids administered intravenously until he feels better.

How to Check Your Dog’s Stomach Temperature

There are a couple of ways that you can check your dog’s temperature.

One of them is by using an infrared thermometer.

This method requires you to hold the device close to your dog’s nose.

The other way is to use a digital rectal thermometer (also called a digital rectal thermometer).

This one works by inserting the probe into your dogs rectum, but only once they’ve been sedated.

Both methods work well, but they each have their own drawbacks.

For example, if you try to use an infrared thermometer on a dog that has just been eating, it will give you a reading that is too high.

The same thing goes for a dog that has diarrhea, which causes its rectum to expand.

Both these conditions make it difficult to get a good reading from a digital rectal thermometer.

Another problem that you might encounter when checking your dog’s temperature is that it may not register correctly.

A dog’s temperature can vary depending on how much fat is in its skin, so there is some room for error.

Also, you should never take your pet’s temperature while they are sleeping.

They are more likely to wake up during the night and move around.

These movements interfere with the accuracy of a digital rectal thermometer.

And finally, don’t confuse the temperature of your dog’s rectum with their core body temperature.

So what exactly does this mean?

Well, let’s say that you want to know whether your dog has a fever.

You could check their temperature with a digital rectal thermometer, but that won’t tell you anything about whether they actually have a fever.

What you need to do instead is take their temperature orally.

If you find out that their temperature is higher than normal, then you know that they have a fever.

But what if they aren’t showing any signs of illness at all?

In that case, you need to get them to the vet as soon as possible.

Here are some things that you should consider before doing so.

When to Seek Veterinary Care for Your Dog’s Warm Stomach

To determine if your dog has a fever, first check their temperature with your hand.

You can do this by placing one finger on your dogs forehead (the area between their ears), then placing another finger on your own wrist.

The difference in the two temperatures should be about 1 degree Fahrenheit.

If you notice that your dog’s temperature is higher than 99 degrees Farenheit, it is possible that they are having trouble breathing.

If so, call your vet immediately and let them know what happened.

A fever can cause serious health issues such as kidney failure, seizures, and even death.

A dog who is experiencing extreme diarrhea may also have a fever.

This is especially true if the diarrhea is accompanied by vomiting.

If your dog is displaying any of these symptoms, contact your vet right away.

In addition to a fever, other signs that your dog might need veterinary care include a weak or lethargic demeanor, restlessness, lack of appetite, excessive drooling, and difficulty walking or standing.

Your dog may also vomit several times per day.

If you suspect that your dog has a mild illness, you can give them some home remedies to help ease their discomfort.

If you notice that your dog is suffering from a more severe case of an illness, however, seek immediate medical attention.

Read on to learn how to check your dog’s temperature.

One way to gauge whether your dog needs medical treatment is by observing their behavior.

If they seem lethargic, sluggish, or unresponsive, see if you can coax them into eating something.

If they refuse to eat, or become extremely aggressive when you try to feed them, it is time to take them to the vet.

It is important to keep track of all medications that your dog takes — including over-the-counter medicines and supplements.

If you notice that your dog’s behavior changes after taking certain medications, or if you think that your dog may be allergic to one particular medication, it is best to bring all of their prescription medications and supplements to your vet.

You should also schedule regular visits to your vet, regardless of how healthy your dog appears to be.

Even if you think that they are fine, there may be underlying conditions that you don’t realize.

Sometimes it is better to catch small problems early rather than wait until they are much worse.

Some illnesses are easier to treat than others.

For example, if your dog suffers from a urinary tract infection, they will likely show obvious signs of pain or discomfort.

However, if they suffer from a condition like heartworm disease, they may not display any symptoms at all.

In order to detect heartworms in your dog, you’ll need a blood test.

If you aren’t sure if your pet has a problem, you can ask your vet to perform a physical exam.

During this exam, your vet will listen to your dog’s heart and lungs, feel their abdomen, and examine their skin.

If your dog’s stomach is unusually warm, you should check with your vet to find out what is causing the increase in temperature.

They may recommend giving your dog fluids through a syringe or feeding them a special diet designed to reduce the chance of overheating.

Prevention of a Warm Stomach in Dogs

If your dog has a warm stomach, there are several things you can do to help them feel better.

Keep them hydrated

Drink plenty of water every day (at least 8-10 cups) and make sure they drink more if they seem thirsty.

Water also helps keep their tummies from getting too full.

Feed your dog small meals throughout the day (instead of one large meal)

This will prevent them from feeling so full that their tummy becomes bloated and causes the heat to build up inside.

Give them some time to rest after eating

This will allow their digestive system to slow down and release any excess heat.

Try not to feed them something very hot – like chili, coffee or soup

These foods cause the temperature of their stomach to rise quickly, which makes it difficult for their bodies to cool off.

Check the weather before taking your dog out

It’s important to avoid extreme temperatures when exercising your pet.

Heat and humidity can increase the chances of overheating and lead to a warm stomach.

Keep an eye on your dog during exercise

When your dog is running around the yard, make sure they’re drinking water and don’t get overheated.

In addition, try to avoid strenuous activity during extreme temperatures.

Exercise your dog regularly

Exercise releases endorphins, chemicals that reduce pain and help decrease stress levels.

This can help your dog feel better faster and give them a boost of energy.
