Heart failure is a common condition that affects many dogs, particularly as they age. It occurs when the heart is unable to pump blood effectively, leading to a range of symptoms and potentially life-threatening complications. While heart failure can be managed with appropriate veterinary care, it is important for dog owners to be aware of the signs of heart failure so that they can seek treatment promptly if their pet develops this condition.
There are many signs that a dog may be experiencing heart failure, ranging from subtle changes in behavior to more obvious physical symptoms. Some of the most common signs include coughing, wheezing, and difficulty breathing, which can be caused by fluid buildup in the lungs. Other signs include fatigue, lethargy, and weakness, which may be due to decreased blood flow to the muscles and organs. Dogs with heart failure may also experience cyanosis, which is a bluish discoloration of the gums, tongue, and other tissues, as well as distension of the abdomen and collapse or sudden death in severe cases.
Understanding Heart Failure in Dogs
Heart failure is a common condition in dogs that occurs when the heart cannot pump enough blood to meet the body’s needs. It can be caused by a variety of factors, including genetic predisposition, age, obesity, and underlying health conditions.
There are two types of heart failure in dogs: left-sided and right-sided. Left-sided heart failure occurs when the heart cannot pump blood effectively to the body, causing fluid to build up in the lungs. Right-sided heart failure occurs when the heart cannot pump blood effectively to the lungs, causing fluid to build up in the abdomen and legs.
The most common cause of heart failure in dogs is mitral valve insufficiency, a condition where the mitral valve in the heart does not close properly, allowing blood to flow backward into the left atrium. Other causes include dilated cardiomyopathy, a condition where the heart muscle becomes weak and enlarged, and heartworm disease, a parasitic infection that can damage the heart and lungs.
Symptoms of heart failure in dogs can vary depending on the severity of the condition and the underlying cause. Some common signs include coughing, difficulty breathing, fatigue, loss of appetite, and weight loss. As the condition progresses, dogs may also experience fainting, abdominal swelling, and difficulty walking or standing.
If you suspect that your dog may be experiencing heart failure, it is important to seek veterinary care as soon as possible. Your veterinarian can perform a physical exam, run diagnostic tests, and develop a treatment plan tailored to your dog’s specific needs. Treatment options may include medications to manage symptoms, dietary changes, and in severe cases, surgery or hospitalization.
In conclusion, heart failure is a serious condition that can significantly impact a dog’s quality of life. By understanding the causes and symptoms of heart failure in dogs, pet owners can take steps to ensure early detection and prompt treatment, improving their dog’s chances of a happy and healthy life.

Physical Signs of Heart Failure
Heart failure is a progressive condition that affects the heart’s ability to pump blood effectively. As the condition worsens, fluid can accumulate in the lungs and other parts of the body, leading to a range of physical signs. Here are some of the most common physical signs of heart failure in dogs:
- Coughing: Coughing is a common sign of heart failure in dogs. It may be dry or moist and may be more frequent at night or after exercise. Coughing can be caused by fluid buildup in the lungs or irritation of the airways.
- Difficulty breathing: Dogs with heart failure may have difficulty breathing, especially when they are lying down. They may breathe rapidly or shallowly, and their breathing may be noisy or labored.
- Fatigue: Dogs with heart failure may tire easily and may be less active than usual. They may seem lethargic or uninterested in activities they normally enjoy.
- Weakness: Dogs with heart failure may have weak or wobbly legs and may have trouble standing or walking. They may also be more prone to falls or accidents.
- Blue or gray gums: In severe cases of heart failure, dogs may have blue or gray gums, which is a sign of poor oxygenation.
- Swollen abdomen: Dogs with heart failure may have a swollen or distended abdomen due to fluid accumulation.
- Weight loss: Dogs with heart failure may lose weight, especially if they have a decreased appetite or are unable to eat due to breathing difficulties.
- Increased heart rate: Dogs with heart failure may have an increased heart rate, even when resting. This is due to the heart’s decreased ability to pump blood effectively.
It is important to note that not all dogs with heart failure will display all of these physical signs. Additionally, some of these signs may be present in other conditions as well. If you suspect your dog may be experiencing heart failure, it is important to consult with a veterinarian for an accurate diagnosis and appropriate treatment.
What are the stages of heart failure in dogs?
Heart failure in dogs is a chronic condition that can worsen over time. There are several stages of congestive heart failure, and each stage is characterized by specific symptoms and changes to the heart.
Stage A
In stage A, the dog is high-risk for CHF but has no symptoms and no changes to the heart. This stage is typically identified during routine check-ups or when the dog is being evaluated for other health issues. At this stage, the veterinarian may recommend lifestyle changes, such as weight management and exercise, to reduce the risk of developing CHF.
Stage B1
In stage B1, the dog has a heart murmur but no other signs of CHF. A heart murmur is an abnormal sound heard during a physical examination that indicates turbulent blood flow in the heart. At this stage, the dog may not require any treatment, but regular check-ups and monitoring are recommended.
Stage B2
In stage B2, the dog has a heart murmur in addition to structural changes to the heart, but no clinical signs of CHF. Structural changes may include enlargement of the heart or thickening of the heart walls. At this stage, the veterinarian may recommend medications, such as ACE inhibitors or beta-blockers, to manage the condition and prevent the progression of CHF.
Stage C
In stage C, the dog has a heart murmur, structural changes to the heart, and clinical signs of CHF, such as coughing, difficulty breathing, and exercise intolerance. At this stage, the veterinarian may recommend additional medications, such as diuretics or vasodilators, to manage the symptoms and improve the dog’s quality of life.
Stage D
In stage D, the dog has end-stage CHF, and medical management is no longer effective. The dog may experience severe respiratory distress, fluid accumulation in the lungs or abdomen, and other complications. At this stage, the veterinarian may recommend hospice care or humane euthanasia to alleviate the dog’s suffering.
