Have you ever wondered what a dog's heart is like? How fast does the heart beat? What does it mean when the heart beats faster or slower than normal? And how can you help him to keep his heart healthy?


In this article, you'll learn everything you need to know about your dog's heartbeat. We explain how you can measure your dog's heart rate, what factors influence it and what signs may indicate heart disease. We also give you tips on how you can protect your dog from heart problems and improve his quality of life.

How do you measure a dog's heart rate?

A dog's heart rate is the number of heartbeats per minute. It varies depending on the dog's age, size, breed and activity level. In general, the smaller the dog, the faster its heart beats.

To measure your dog's heart rate, you will need a stethoscope or a watch with a second hand. Lay your dog on his side or hold him in your arms and listen for his heartbeat with the stethoscope or your ear. You can hear it either on the chest or on the inside of the thigh. Count the number of beats for 15 seconds and multiply by four to get the heart rate per minute.

A dog's normal heart rate is between 60 and 140 beats per minute. Puppies and small dogs have a higher heart rate than adult and large dogs. If your dog is very excited or nervous, his heart may also beat faster. If you are unsure whether your dog's heart rate is normal, you should consult a vet.

What affects a dog's heart rate?

A dog's heart rate can be affected by various factors. Some of these are:

  • Age: Puppies have a higher heart rate than adult dogs because their hearts are not yet fully developed. The heart rate decreases with age.
  • Size: Small dogs have a higher heart rate than large dogs because their heart has to work harder to supply the whole body with blood.
  • Breed: Some dog breeds have a higher or lower heart rate than others. For example, greyhounds have a lower heart rate than other dogs because they have a larger chest and a larger heart.
  • Activity level: When your dog is exercising or playing, his heart rate increases to transport more oxygen and nutrients to his muscles. When he rests or sleeps, his heart rate drops again.
  • Emotions: When your dog experiences fear, stress or joy, his heart may beat faster or slower. For example, his heart may beat faster when he sees another dog or when you come home. His heart may beat slower when he is relaxed or tired.
  • Temperature: When it is very hot or cold, your dog's heart rate may change. For example, his heart may beat faster when he is overheated or cold.
  • Health condition: If your dog is sick or has a heart condition, his heart rate may be abnormal. For example, his heart may beat faster when he has a fever or is in pain. His heart may beat slower if he has heart muscle weakness or heart block.

What signs can indicate heart disease?

Heart disease is a serious condition that can put your dog's life at risk. Unfortunately, many dogs have no obvious symptoms until the disease has progressed. That's why it's important to have your dog checked regularly by a vet and to look out for possible signs. Some of these include:

  • Irregular heartbeat: When measuring your dog's heart rate, look for a steady rhythm. If you hear skips, extra beats or a stumble, this may be a sign of a cardiac arrhythmia.
  • Fast or weak breathing: If your dog is breathing faster or harder than normal, this may be a sign of heart failure. This means that his heart is not pumping enough blood to his body and fluid is building up in his lungs. When measuring your dog's breathing, look for a rate of 10 to 30 breaths per minute. When you touch your dog's chest, you should feel a strong flow of air.
  • Coughing: If your dog coughs frequently, especially at night or after getting up, this may be a sign of heart failure. The cough is caused by fluid in the lungs irritating the airway.
  • Fatigue or weakness: If your dog is less active or lively than usual, this may be a sign of heart disease. He may tire more quickly or refuse to play or go for a walk. He may also have problems climbing stairs or jumping onto the sofa.
  • Pale or blue mucous membranes: When you look at your dog's tongue, gums or eyelids, look for a rosy color. If they are pale or blue, this can be a sign of poor circulation. This means that his heart is not transporting enough oxygen to his body.
  • Fainting or collapsing: If your dog suddenly loses consciousness or collapses, this can be a sign of severe heart disease. This can happen if his heart suddenly stops beating or if he has a heart attack.
  • Belly swelling: If your dog's belly is swollen or hard, this can be a sign of heart failure. This means that fluid is accumulating in the abdominal cavity.

If you notice one or more of these signs in your dog, you should see a vet immediately. Early diagnosis and treatment can save your dog's life.

How can you keep a dog's heart healthy?

While you can't prevent all heart disease, there are some steps you can take to reduce the risk and promote your dog's health. Some of these are:

  • Feedyour dog high-quality food: A balanced diet is important for your dog's health. Choose food that is appropriate for their age, size and activity level. Avoid food with too much salt, fat or sugar, which can increase blood pressure and strain the heart.
  • Keep your dog slim: Obesity is one of the most common risk factors for heart disease in dogs. Excess weight puts a strain on the heart and increases blood pressure and cholesterol levels. To keep your dog slim, don't give him too much food and don't feed him table scraps or treats.
  • Exercise your dog regularly: Exercise is good for your dog's heart. It strengthens his muscles and circulation and keeps him fit and happy. You should take your dog for a walk at least once a day.
