What is Heart Beating Fast?
Depending on the size of your dog, a faster heartbeat could be completely normal. Smaller dogs tend to have much faster heartbeats than larger dogs, so it is important to understand what is normal for your particular dog. Tachycardia simply refers to an abnormally quick heartbeat. Besides size, however, there are a few other reasons why your dog may be having a faster heartbeat than usual. This heart issue can be defined a couple of different ways. The first being tachycardia, which means an abnormally fast heart rate. And secondly, arrhythmia, which is the irregular rhythm of a heart. Listed below are a few of the reasons why your dog may be experience a fast heartbeat:
- Heart disease
- Drug overdose
- Congestive heart failure
- Gastrointestinal disease
- Ventricular tachycardia
- Supraventricular tachycardia
If you notice that your dog is having a faster heartbeat than usual, it is vital to get him to a vet as soon as possible. Hearts are very difficult to repair once damage has been done and damage can lead to death if left untreated. So, if you suspect that anything is off, medical attention will be necessary in order to diagnose the issue further. It is always better to be safe than sorry, therefore do not hesitate to get medical help if your dog is showing signs of rapid heartbeat, excessive panting, shortness of breath, lethargy, weak pulse, or fever.

Why Heart Beating Fast Occurs in Dogs
When determining why your dog may have a fast heartbeat, it is important to remember that size does play a part in heart pace. Smaller dogs, even those in perfect health, will have a faster heartbeat than a larger dog. Small dogs and puppies typically have a normal heartbeat of around 120 to 160 beats per minute. Larger dogs, over 30 pounds, tend to have a slower pace at around 60 to 120 beats per minute. If your dog is over the average speed for his weight category, he could be victim to heart disease, drug overdose, congestive heart failure, gastrointestinal disease, ventricular tachycardia, or supraventricular tachycardia. As the first line of defense for your pet, understanding heart issues will help to ensure that you recognize an issue and can act accordingly. Read the descriptions below to learn a bit about what each of these underlying issues are and be sure to speak with your vet immediately if you suspect your dog is suffering from one of them.
Although it is unfortunate to hear, heart disease in dogs is actually quite common. There are many reasons why problems in the heart occur and each one can lead to heart failure if not treated immediately. Monitor your pet closely and if you notice any signs of heart disease such as coughing, lethargy, and loss of appetite take your dog to the vet as soon as possible to be examined.
Heart medicine poisoning can take place when there is too much of a drug in the bloodstream of a dog at one time. This can happen due to accidental ingestion or by human error. Even if the dog has been specifically prescribed a heart medicine, too much of it can poison the heart. Once this happens the toxicity can either occur very quickly, known as acute, or it can take effect over a long period of time which is known as chronic. Regardless of the speed toxicity occurs, it is vital to get your dog immediate treatment in order to minimize the damage.
Congestive Heart Failure
The two most common causes of CHF (congestive heart failure) are mitral valve insufficiency and dilated cardiomyopathy, both of which are a type of valvular insufficiency. While the terms may seem complicated, the definition of CHF is simply that a heart no longer has the ability to adequately move blood throughout the body. It is important to pay close attention to your dog’s behavior. The symptoms that appear with congestive heart failure will depend on which side of the heart is failing. Commonly, dogs will show signs of CHF through coughing, low stamina, loss of appetite, swollen belly, blue gums, or difficulty breathing. If you notice any of these signs paired with a rapid heartbeat, schedule an examination with the vet immediately.
While it may not seem that a problem in the digestive tract would affect the heart, the two systems actually share disorders quite commonly. It is a very complicated relationship, however it’s been noted that those with gastrointestinal disease (which can be a blockage and inflammation) can also suffer from cardiac issues as well. This is most likely due to the inflammation that occurs within the digestive tract as a result of damage or blockage, either from food or some foreign body. Monitoring your dog’s behavior is vital if you believe that he has gastrointestinal disease. Catching it early can help prevent any damage from affecting the heart. If you see that your dog has trouble defecating, becomes extremely weak, experiences any abdominal pain, or has blood in the feces, you will want to take your dog to the vet immediately for medical attention.
As mentioned previously, tachycardia is defined as an abnormally rapid heart rate. This issue meddles with the rhythm of the heart through its own electrical impulse.
In order to understand ventricular tachycardia properly, we must first look at the location it takes place inside the heart. Within the heart there are chambers called ventricles which are responsible for pumping blood in and out of the heart and on to the rest of the body. Ventricular tachycardia occurs within these ventricles. Because of the increased heartbeat, the ventricles do not have time to fill up completely with blood before the heart contracts; meaning that the blood then does not get pumped through the body correctly.
Some symptoms that can occur with ventricular tachycardia are:
- Shortness of breath
- Chest pain
- Rapid heartbeat
When Ventricular tachycardia occurs, there are some cases where the body can adapt just fine; however, the issue can be life threatening, so it is vital to seek medical attention immediately if you suspect that your dog is suffering from any of these symptoms.
Similar to ventricular tachycardia, supraventricular tachycardia has the same symptoms but occurs in the atria of the heart situated above the ventricles. This issue can occur in both dogs who do and do not have structural heart disease and can be categorized as a type of arrhythmia (irregular heart rhythm). If you notice that your dog is showing any of the symptoms mentioned above, it is vital to see a vet immediately in order to maintain the health and structure of your dog’s heart.
What to do if your Dog is Heart Beating Fast
It can be quite alarming to discover that your dog’s heart it beating a bit too fast for comfort. But quite often, it may just be that you’ve never thought about the normal heart rate for your pet. Smaller dogs, under 30 lbs. tend to have a much faster heartbeat than larger dogs, around 120 to 160 beats per minute. Larger dogs over 30 lbs. should have a heartbeat of about 60 to 120 beats per minute. The best way to determine your dog’s heart rate is to follow these steps:
- Grab a timing device (clock, watch, smartphone)
- Place your hand over the left side, just behind the front leg
- Count the number of beats in 15 seconds, then multiply by four to get the heart rate in bpm (beats per minute)
Because normal heartbeats can vary, it may be difficult to get a correct reading the first time without a baseline. So perform the test a few times before making any assumptions. If what you find is concerning to you, then be sure to set up an appointment for your dog with the vet as soon as possible.
Prevention of Heart Beating Fast
A lot of heart issues can stem directly from diet. If your dog has an unhealthy gut, then he may develop heart problems in the future. It is important to ensure that your dog is getting plenty of exercise and a balanced diet free of an overabundance in fatty foods. By doing this, you can help lower the chances of your dog developing heart issues significantly.
Unfortunately, there are some cases where heart defects are inevitable. Genetics can pass along a heart problem as well as cases where trauma (such as vehicle accident) is the main reason for increased heart rate or heart failure. The most important thing to remember is that no matter what the cause of your dog’s fast heartbeat may be, getting him to the vet for treatment as soon as possible is the best thing that you can do. Surgery or medications may be able to stop any further damage from occurring so that your pet can live a full life. Understand what the normal heartbeat range is for your dog by performing the test mentioned above and do not hesitate to take action if you suspect that anything is amiss.
Cost of Heart Beating Fast
Treatment cost will vary depending on the cause of your dog’s fast heartbeat. For instance, if your dog is diagnosed with congestive heart failure, the average cost of treatment is $2,500. If your dog is diagnosed with rapid heart rate due to ventricular tachycardia, the cost of treatment can range from $500 to $6,500 depending on the cost of living and the severity.
