To diagnose heart disease in dogs, veterinarians may perform a combination of diagnostic procedures and tests, including listening to the dog’s chest, blood tests, x-rays, electrocardiograms (ECGs), and ultrasounds (WebMD). These tests help to assess the heart’s structure and function, identify potential abnormalities, and determine the most suitable treatment options.
Understanding the basics of canine heart disease, along with recognizing common symptoms, enables dog owners to seek appropriate veterinary care at the earliest signs of a problem. In the following sections, we will delve deeper into the diagnosis, treatment, and specific heart conditions that can affect our furry friends.
Diagnosis and Testing
When it comes to diagnosing and testing for heart disease in dogs, early detection is crucial for effective treatment and management. Veterinary professionals employ various methods to detect and diagnose heart disease in dogs, ensuring the best possible care for our furry friends.
Detecting Heart Disease in Dogs
Detecting heart disease in dogs begins with a thorough examination by a veterinarian. During this examination, the vet will listen to the dog’s chest using a stethoscope to detect any abnormal heart sounds or murmurs. They will also assess the dog’s overall health and ask about any symptoms or changes observed by the owner.
It’s important for dog owners to be aware of common signs of heart disease in dogs, such as persistent cough, fainting or collapse, difficulty breathing, fatigue, inability to exercise, and behavior changes like poor appetite and reluctance to play (Morris Animal Foundation). If you observe any of these symptoms in your dog, it’s crucial to seek veterinary attention promptly.
Diagnostic Procedures and Tests
To confirm the presence of heart disease and determine the specific condition, veterinarians may recommend additional diagnostic procedures and tests. These may include:
-
Chest X-ray: A chest X-ray provides an image of the heart, lungs, and surrounding structures. It helps identify abnormalities in heart size, shape, and lung congestion, providing valuable information for diagnosis and treatment planning.
-
Electrocardiogram (ECG): An ECG records the electrical activity of the heart. It helps identify irregular heart rhythms (arrhythmias) and abnormalities in the heart’s conduction system.
-
Echocardiogram: An echocardiogram is an ultrasound examination of the heart. It allows visualization of the heart’s structures, including valves, chambers, and blood flow. Echocardiography is particularly useful in diagnosing conditions such as valve disease and heart muscle disease (CVCA Cardiac Care for Pets).
-
Blood Tests: Blood tests can provide valuable information about cardiac biomarkers, such as NT-proBNP, which can indicate the presence of heart disease and help evaluate its severity (Morris Animal Foundation). These tests may also include a complete blood count (CBC) to assess overall health and rule out other conditions such as liver disease or kidney disease that can impact heart health.
These diagnostic procedures and tests, when used together, help veterinarians accurately diagnose heart disease in dogs. They enable the veterinarian to determine the specific condition affecting the dog’s heart and develop an appropriate treatment plan. It’s important to consult a veterinary professional experienced in cardiac care to ensure accurate diagnosis and effective management of heart disease in dogs.
Understanding and identifying heart disease in its early stages can significantly impact a dog’s quality of life and overall prognosis. Regular check-ups with a veterinarian and awareness of potential symptoms are key steps in maintaining the heart health of our beloved pets.

Specific Heart Conditions
When it comes to heart disease in dogs, several specific conditions can affect our furry friends. Understanding these conditions is important for early detection and proper management. In this section, we will explore four common heart conditions in dogs: myxomatous mitral valve degeneration, dilated cardiomyopathy (DCM), heartworm disease, and congestive heart failure (CHF).
Myxomatous Mitral Valve Degeneration
Myxomatous mitral valve degeneration (MMVD) is the most common type of heart valve disease in dogs. It tends to affect older, small-breed dogs. MMVD occurs when the mitral valve, which separates the left atrium from the left ventricle, degenerates over time. This can lead to a leaky valve, causing blood to flow backward into the atrium instead of moving forward into the ventricle as it should.
Early stages of MMVD may not exhibit noticeable symptoms, but as the disease progresses, common signs can include coughing, difficulty breathing, exercise intolerance, and changes in appetite or behavior. Regular veterinary check-ups and diagnostic tests can help detect and monitor MMVD in its early stages.
Dilated Cardiomyopathy (DCM)
Dilated cardiomyopathy (DCM) is a type of heart muscle disease in dogs that occurs when the heart muscle degenerates and thins, making the heart less able to pump blood effectively. DCM can be genetic or linked to dietary deficiencies, such as taurine and L-carnitine. Certain dog breeds, such as Doberman Pinschers and Boxers, are more predisposed to DCM.
Symptoms of DCM can include weakness, exercise intolerance, coughing, difficulty breathing, and even fainting. If left untreated, DCM can lead to congestive heart failure (CHF), a serious condition where the heart fails to pump blood effectively. Regular veterinary check-ups, including echocardiograms and blood tests, can help diagnose and monitor DCM.
Heartworm Disease in Dogs
Heartworm disease in dogs is a serious and potentially life-threatening condition caused by the parasitic worm Dirofilaria immitis. It is primarily transmitted through the bites of infected mosquitoes. Adult heartworms reside in the larger blood vessels of the lungs and the heart, causing inflammation and damage that can block blood flow (PetMD).
Symptoms of heartworm disease can vary, but common signs include coughing, difficulty breathing, fatigue, weight loss, and a decreased appetite. Prevention is key when it comes to heartworm disease, and it is recommended to use preventive medications year-round. Regular veterinary check-ups and annual heartworm testing can help detect the disease early and ensure timely treatment.
Congestive Heart Failure (CHF)
Congestive heart failure (CHF) is a consequence of many types of heart disease in dogs. It occurs when the heart can no longer pump blood effectively, leading to fluid accumulation in various tissues. CHF can be caused by conditions such as MMVD, DCM, or heartworm disease.
Symptoms of CHF may include coughing, difficulty breathing, rapid breathing, exercise intolerance, abdominal distention, and lethargy. Treatment for CHF aims to manage the underlying heart condition and improve the dog’s quality of life. Medications, dietary changes, and lifestyle modifications are often recommended to help alleviate symptoms and slow down disease progression.
By recognizing the specific heart conditions that can affect dogs, owners can work closely with their veterinarians to monitor their pet’s heart health and provide the necessary care. Regular veterinary check-ups, early detection, and appropriate treatment are crucial for managing heart disease in dogs effectively.

Certain dog breeds are more susceptible to specific heart conditions. Understanding the breed-specific risks can help dog owners be proactive in monitoring their pet’s heart health and seeking appropriate veterinary care. Here are some breeds that have a higher predisposition to heart disease:
Cavalier King Charles Spaniels
Cavalier King Charles Spaniels are more prone to degenerative mitral valve disease (DMVD) than any other breed. It is estimated that 50% of Cavaliers develop a heart murmur by the age of 5, and by the age of 10, 100% of them will have a heart murmur. The early symptoms of congestive heart failure in this breed include decreased exercise tolerance, labored breathing, and coughing. Regular veterinary check-ups and early detection are crucial for managing this condition (PetMD).
Doberman Pinschers
Doberman Pinschers are at risk for dilated cardiomyopathy (DCM), a disease that causes the left ventricle of the heart to enlarge and function incorrectly. DCM occurs more frequently in male Dobermans. Symptoms of DCM in Dobermans may include fainting, weight loss, shortness of breath, coughing, or fluid retention. Regular veterinary examinations and diagnostic testing can aid in the early detection and management of DCM in Dobermans.
Boxers
Boxers are susceptible to arrhythmogenic right ventricular cardiomyopathy (ARVC), a genetic heart disease that can lead to life-threatening heart rhythm abnormalities. Symptoms of ARVC in Boxers may include exercise intolerance, fainting, and sudden death. Regular veterinary care, including cardiac evaluations, can help monitor and manage the heart health of Boxers (PetMD).
Golden Retrievers
Golden Retrievers commonly suffer from aortic stenosis, a congenital heart disease where the aortic valve doesn’t form properly during gestation. This condition may be apparent at birth or within the dog’s first year. Routine veterinary check-ups and early detection are vital for managing aortic stenosis in Golden Retrievers. Treatment options may include medication and, in severe cases, surgical intervention (PetMD).
Labrador Retrievers
Labrador Retrievers are also prone to dilated cardiomyopathy (DCM), similar to Doberman Pinschers. Regular veterinary check-ups and diagnostic testing can help detect and manage DCM in Labrador Retrievers. Early intervention is important to ensure the best possible outcomes for affected dogs.
Dachshunds
Dachshunds typically develop a leaky heart valve, known as degenerative mitral valve disease (DMVD), between 8 and 10 years of age. Regular annual veterinary check-ups are recommended to detect this condition early. As the dog ages, more frequent examinations, every six months, are advised to monitor the progression of the disease. Early detection and appropriate management can help improve the quality of life for Dachshunds with DMVD.
By being aware of the breed-specific risks for heart disease, dog owners can work closely with their veterinarians to monitor their pet’s heart health and take proactive measures to manage and treat any conditions that may arise.
