Why My Dog Died Suddenly Tongue Out?

It can be a difficult experience. It is difficult to accept the loss of a dog you love and it is even more so when it happens suddenly.

Dog owners often ask questions. You might also want to know why your dog suddenly lost its tongue.

Dogs can have their tongues pulled out by a heart attack, respiratory attack, or other reasons. It is common for a dog to have its tongue hanging out after death if it doesn’t get enough oxygen. The root cause of the blue tongue was probably lack of oxygen.

To find out more about why your dog died, it’s best that you consult with your vet. Although it can be distressing for dog owners, it is important to find out the cause of death.

This article will explain why a dog’s tongue pops out after it dies.

Why a Dog Died Suddenly With its Tongue Out

Heart Attack

This is the leading reason dogs die from their tongues sticking out.

Dogs can experience heart problems such as fatigue, pain, and the inability to reach certain places without getting their breath caught. This could become a chronic issue that can cause a rapid decrease in oxygen levels.

Dogs eventually die from lack of oxygen. However, the dog’s heart is what ultimately gives way. This is why a dog’s tongue hangs out when it dies.

Dogs that are suffering from a heart attack will often pant.

This is due to the stress on the dog’s body and the difficulty it has to move. Dog owners often mention that their dog’s tongue hangs out after it has died from a heart attack.

Respiratory Issue

This could be the reason why a dog suddenly died with its tongue out.

A tongue can have asthma attacks or become suffocating. It’s not uncommon for the tongue to turn blue if there is a persistent lack of oxygen. This can make it difficult for dogs to manage.

Sometimes, dogs will begin to pant heavily in their final days. This happens because of the stress placed on the lungs each time the dog takes a deep breath.

The tongue turns blue as more oxygen is removed from the body. The dog may also die with its tongue out.


This depends on the activity of the dog.

It is possible that a dog can be injured if it falls from great heights or gets hit by something.

A dog may start to pant heavily when this happens, which can cause stress to the lungs. The dog will eventually lose its tongue and end up passing away.

If an injury occurred before the death, that is likely to be the reason.


Although it is uncommon, this could be a sign that the dog’s tongue was out at the time of his death.

The infection may spread to other parts of your body. The body may experience a decrease in oxygen availability.

Carbon dioxide can build up inside the body when there isn’t enough oxygen. This is why dogs feel uncomfortable taking full, deep breaths.

The dog eventually dies with his tongue out.


Many dog owners don’t know that bloat is a serious condition. Gastric dilation-volvulus is another name for this fatal condition.

It involves twisting the stomach. The abdomen can become very bloated and swollen from the gas trapped.

Dogs can die if they are not treated promptly.

This deadly condition can be caused by strenuous exercise right after eating and drinking, as well as excessive water intake.

It is more common in large, deep-chested dogs but smaller dogs can also be affected.


Heartworm disease can cause heart failure and other organ damage. It can also cause sudden death.

The disease is caused by a parasitic worm. The parasitic worms are toxic and can twist and turn around the insides of your pet.

Heartworm-infected dogs can develop a cough, difficulty breathing, unusual weight loss, and a swollen stomach. Heart failure can occur, which can lead to death.

Puppies Can Also Die Suddenly

It is shocking, but it is a fact: sudden death in dogs is a harsh reality.

This is fading puppy Syndrome. It can occur within the first few weeks of a puppy’s life. It could be a birth defect or something else that is not immediately obvious.

This could be a puppy who is weak and has a poor immune system.

Another common cause of fading puppies syndrome is canine herpesvirus. It can lead to sudden death in puppies as young as one-year-old.

It is possible that the puppy had low birth weight, diarrhea, been neglected by its mother, or difficulty breathing.

To check on the puppies, you can look for a pup with a hanging tongue.

Keep Toxins Out of Reach

Puppies need constant supervision. They can wander off if you aren’t there.

Many puppies inhale toxic substances such as pool chemicals and medications. Sudden death is common in adult and puppy dogs who have ingested toxins.
