Heart disease in pets is more common than many owners realize. From congenital issues to age-related conditions, understanding the most common heart problems can help you recognize symptoms early and get your pet the care they need. The good news is, that many cardiac conditions are treatable and manageable with the proper medication, lifestyle (such as diet and exercise), and regular visits with your primary care veterinarian or a specialist.
Here are some common heart problems seen in pets. Keep in mind that many symptoms can be similar among them, which is why it’s crucial to work with veterinary professionals for an accurate diagnosis and appropriate treatment plan.
1. Congestive Heart Failure (CHF)
Congestive heart failure occurs when the heart has trouble pumping blood efficiently, leading to fluid buildup in the lungs or abdomen. This condition is more common in older dogs, especially smaller breeds like Dachshunds and Cavalier King Charles Spaniels. Symptoms can include coughing, difficulty breathing, lethargy, and loss of appetite. The good news is that with regular care, and proper treatment – including medication to reduce fluid buildup and support heart function – pets can feel more comfortable and continue to enjoy their daily activities.
2. Heartworm Disease
Heartworm disease is caused by parasitic worms transmitted through mosquito bites, affecting the heart and lungs. While it’s more common in dogs, cats can also be impacted. In dogs, symptoms might include coughing, fatigue, and weight loss, while in cats, you may notice coughing, vomiting, or labored breathing. The good news is that heartworm disease is preventable with the right medication, making it easy to protect your pet and help keep them healthy and happy.
3. Dilated Cardiomyopathy (DCM)
Dilated cardiomyopathy (DCM) is a condition where the heart muscle becomes a little weaker and stretched, which can affect its ability to pump blood effectively. It’s more commonly seen in larger dog breeds, like Doberman Pinschers and Great Danes, but can also affect other breeds. Some signs to watch for include tiredness, coughing, occasional fainting, or fluid buildup in the belly. While DCM can progress over time, early diagnosis and the right medication can help manage the condition and keep your pet comfortable.
4. Hypertrophic Cardiomyopathy (HCM)
Hypertrophic cardiomyopathy (HCM) is the most common heart condition in cats. It happens when the heart muscle becomes thicker, which can make it a bit harder for the heart to pump blood. Some breeds, like Maine Coons and Ragdolls, may be more likely to develop HCM due to genetics. Signs to watch for include faster breathing, feeling more tired than usual, or occasional weakness. While there’s no cure for HCM, medication can help manage symptoms and improve your cat’s comfort and well-being.
5. Valvular Heart Disease
Valvular heart disease is more common in older dogs, especially in small breeds like Cavalier King Charles Spaniels and Yorkies. It happens when the heart valves don’t close quite as they should, which can cause some mild strain on the heart. Signs to watch for include coughing, trouble breathing, or feeling less active than usual. With the right medication, the condition can be managed to help keep your pup comfortable and possibly prevent further issues.
