Is It True That Dogs Have 2 Hearts?
Dogs Heart Anatomy Explained

No, dogs do not have two hearts. Like us, dogs have only one heart. However, like our heart, the canine heart also has four chambers. The two upper chambers are called the left and the right atria and the two lower chambers are called the left and right ventricles.

The dog cardiovascular system includes the heart and the blood vessels, i.e. the veins and the arteries.  The function of the heart is to pump oxygenated blood to the rest of the body. Without a heart there is no life, it is as simple as that.

“the animal with the largest heart-to-body-mass ratio is somewhat surprising: the dog. Compare a dog’s heart to its body mass and it’s a .8 percent ratio. Almost all other animals — including elephants, mice and humans — have a .6 percent ratio. Another animal with a ratio larger than most mammals is the dog’s ancestor, the wolf”

What Is Normal Dogs Heart Rate?

It is perfectly normal for healthy dogs to have irregular heart rate. The heart rate increases when the dog breaths in and decreases when he breaths out. This heart rhythm is called respiratory sinus arrhythmia and is a sign of a good canine heart health. 

Normal heart rate in dogs depends on the size of the dog. Larger dogs have slower heart rate than smaller dogs. It is normal for small dogs and puppies to have heart rate of 120 – 160 beats per minute while normal heart rate for larger dogs (over 14 kg / 30 pounds) is between 60 – 120 heart beats per minute. 

If your dog’s heart rate is outside of the normal range, then you should contact your veterinarian immediately.

Which Dog’s Are Most Likely to Get Heart Disease?

Some dog breeds are unfortunately more prone to heart problems than other dog breeds. These includes popular dog breeds like Golden Retrievers, Boxers, Miniature Schnauzers, Cavalier King Charles Spaniels, Dachshunds, Doberman Pinschers, Chihuahua, Boston Terrier, Miniature and Toy Poodles.

It is important for the owners of those dog breeds to be aware of the risk so they can keep an eye on any symptoms of potential heart problems. They may also want to take some preventive measures to keep their dog’s heart as healthy as possible.

What Are the Most Common Dog Heart Disease Symptoms?

Dogs can be born with heart disease, i.e. genetic heart disease. However, canine heart disease is much more likely to be acquired over the years of wear and tear, or to be the result of illness or injury. 

These are the most common symptoms of heart problems in dogs:

- Pale gums

- Shortness of breath

- Fatigue and fainting spells

- Unexplained rapid weight loss

- Dry coughing after exercise session

- Increased coughing at night

- Decreased appetite

- Swollen abdomen

If your dog shows sign of one or more of the above heart disease symptoms, then you should seek medical help. 

How Can You Best Support Your Dogs Heart?

There are things that dog owners can do to keep their dog’s heart as healthy as possible.

Good Dental Care

This may come as a surprise but there is a strong correlation between gum health and heart disease so good dental care is more important than most dog owners realise. 


Regular cardiac exercise, like walking, running, playing, swimming and hiking, will not only keep your dog’s heart healthier, it will also keep your dog happy and content. 

Balanced Diet

We are what we eat and the same applies to our dogs. Healthy nutritious diet will help to keep your dog’s heart healthy for longer.

Weight Management

Frequent cardiac exercise and good nutritious diet will help to keep your dog’s weight within the healthy range and minimize the strain on his heart.

Parasites Prevention

Heartworms are thought to cause around 12-15% of all heart disease cases in dogs so heartworm preventives are very important. Parasites, like fleas and ticks, can also cause stress on the heart.


There are natural supplements available that support and nurture good heart health. The most important thing is to chose one with the best ingredients for your dog’s cardiovascular health. 

Annual Vet Exams

Checking your dogs heart health should be part of your dog’s annual Vet exam. Because like with all health problems, early detection of any heart problems can make all the difference for your dog.
