Heart Health for Pets: Recognizing the Signs of Heart Disease

Heart disease doesn’t just affect humans. It’s also a serious concern for our four-legged family members. At Coal Creek Animal Hospital in Lafayette, CO, we know that a strong heart is key to a long, happy life for your pet. And while our furry friends can’t tell us when something feels off, they often show us, if we know what to look for.
Let’s explore the signs of heart disease in pets, how you can stay proactive with pet cardiology care, and what a routine pet heart check-up can reveal about your pet’s well-being.
Common Signs of Heart Disease in Pets
Cats and dogs tend to hide discomfort and illness, which can make detecting heart disease tricky. But subtle changes in behavior or appearance often speak volumes.
Here are some signs that may point to a heart issue:
- Coughing that persists or worsens, especially at night or after lying down
- Fatigue or weakness, particularly during exercise or walks
- Rapid or labored breathing, even while resting
- Fainting or collapsing episodes
- Decreased appetite or weight loss
- Swollen abdomen due to fluid buildup
- Pale or bluish gums
It’s easy to chalk these symptoms up to aging or an off day, but they may signal something more serious. Early diagnosis improves outcomes, so if anything seems off, it’s worth getting it checked out.
Dog Heart Murmurs: What Do They Mean?
Hearing that your pup has a heart murmur can be alarming, but not all murmurs are cause for alarm. A murmur simply means there’s turbulent blood flow in the heart, which your veterinarian can detect during a physical exam.
There are two main types:
- Innocent murmurs, often found in puppies and usually harmless
- Pathologic murmurs, which may indicate structural heart disease
Whether your dog’s heart murmur requires monitoring or treatment depends on its cause and severity. Regular pet heart check-ups allow us to track changes over time and take action if needed.
Cat Heart Care: A Unique Challenge
Cats are masters of disguise, especially when it comes to heart disease. Unlike dogs, they rarely cough as a symptom. Instead, many cats with heart issues may simply become more withdrawn or less active.
One common condition in cats is hypertrophic cardiomyopathy (HCM), in which the heart muscle thickens and struggles to pump blood efficiently. This can lead to fluid buildup, blood clots, and even sudden collapse if left unchecked.
Because signs are subtle, routine exams and early screenings are vital. At Coal Creek Animal Hospital, our feline friends receive gentle, Fear Free care that keeps stress low and allows us to focus on their health.
The Role of Routine Pet Heart Check-Ups
A wellness visit isn’t just about vaccines and ear checks. It’s also an opportunity to monitor your pet’s heart. During a physical exam, we’ll listen for murmurs, irregular rhythms, or other red flags. If needed, we may recommend further diagnostics such as:
- Digital X-rays to visualize the heart and lungs
- Ultrasound for detailed imaging
- Blood pressure measurements and lab testing
These tools help us catch concerns early and tailor a treatment plan that supports your pet’s lifestyle.
How Pet Cardiology Support Helps
Managing heart disease in pets often involves a combination of:
- Medications to support heart function and reduce fluid buildup
- Dietary adjustments to lower sodium and support organ health
- Regular monitoring to track symptoms and treatment response
- Activity guidance to keep your pet safe but active
Each case is unique, and our team works closely with you to create a plan that fits your pet’s needs and personality—because no two hearts are alike.
