Does CBD Oil Offer a Helping Paw for Dogs With Heart Disease?

Heart disease in dogs is a heartbreaking (pun intended) reality for many pet owners. From congenital issues lurking since birth to conditions that pop up with age, heart disease isn’t just a human issue—it affects furry friends, too. As daunting as that sounds, there are ways to help manage it, including a new natural superstar: CBD oil. Yep, CBD for dogs with heart disease is becoming a real game-changer, offering a holistic approach to easing symptoms, supporting heart health, and giving pet parents more options than ever.

Ready to dive into the heart (again, pun intended!) of canine cardiovascular care? Let’s break down what CBD oil does for a dog’s heart health, why it’s worth considering, and how it fits in alongside other treatments.

Heart Disease in Dogs: The Basics

First, it’s good to talk about what canine heart disease entails. Like humans, dogs’ hearts suffer from conditions that impact their ability to pump blood effectively. Some of the big players regarding doggy heart disease are listed below.

Congestive Heart Failure (CHF): It occurs when the heart is unable to pump blood normally. It causes fluid buildup in the lungs and other areas, leading to classic panting and struggling to catch a breath. A study in the Journal of Veterinary Internal Medicine concluded that “Cardiac cachexia is common in dogs with congestive heart failure and is associated with significantly shorter survival times, emphasizing the importance of preventing, diagnosing, and treating muscle loss,” (Ineson, D., Freeman, L., & Rush, J., 2019).

Dilated Cardiomyopathy (DCM): A weakened heart muscle makes it difficult to pump blood effectively, leading to an enlarged heart. A study about canine idiopathic dilated cardiomyopathy showed that “DCM is one of the most common heart diseases in dogs, with some breeds, like Boxers and Doberman pinschers, being affected by both types,” (Tidholm, A., et al., 2001).

Mitral Valve Disease: Often found in small breeds like Cavalier King Charles Spaniels, this disease weakens the heart valve, causing blood to leak backward—a literal heart murmur. According to a study in the Journal of Veterinary Cardiology, “Degenerative mitral valve disease (DMVD) is a significant canine health issue, with age, breed, and body size being strong associations, and the incidence of DMVD in some breeds approaching 100% over a lifetime,” (Orton, E., 2012).

Heartworm Disease: Parasites from mosquito bites make themselves at home in a pup’s heart and blood vessels. If untreated, heartworms lead to irreversible damage. A prevalence study showed that “Canine heartworm infection prevalence is increasing in much of the USA, both regionally and locally, with the largest increase in the Lower Mississippi River Valley,” (Self, S., et al., 2019).

Congenital Heart Defects: Sometimes dogs are born with structural issues in the heart, which strain their cardiovascular system as they grow. A retrospective review of congenital heart disease (CHD) in 976 dogs showed that “CHD was observed in 21.7% of dogs, with the most common defects being pulmonic stenosis (32.1%), subaortic stenosis (21.3%), and patent ductus arteriosus (20.9%),” (Oliveira, P., et al., 2011).

These conditions don’t just affect the heart—they mess with blood flow, blood pressure, and overall cardiovascular health, impacting a dog’s quality of life.

Symptoms of Heart Disease in Dogs

Knowing the signs of heart disease in dogs helps pet parents catch issues early. Some general signs are listed below.

• Difficulty breathing or labored breaths
• Fatigue and decreased exercise tolerance (like getting tired on short walks)
• Frequent coughing (often worse when lying down)
• Changes in appetite or sudden weight loss
• Fainting or sudden weakness
• Abdominal swelling (caused by fluid pooling in the abdomen)
• Bluish tinge to skin and membranes due to a lack of oxygen in the blood

If pet parents are seeing any of these symptoms, it’s time for a veterinary visit. Regular veterinary checkups are essential to catch these conditions early before they progress into something more serious.

The Traditional Approach to Treating Canine Heart Disease

Once diagnosed, the conventional treatment plan listed below is usually utilized.

Prescription Drugs: ACE inhibitors (to relax blood vessels), diuretics (to reduce fluid buildup), and beta-blockers (to help regulate heart rate) are common.

Diet Changes: Low-sodium diets are often recommended to reduce the heart’s workload. Some dog-friendly superfoods—like fish oil for omega-3s and taurine-rich organ meats—are great for heart support.

Heartworm Preventatives: If heartworm is a risk, monthly preventatives are a must.

Surgical Procedures: In some cases, surgery is necessary, especially for severe congenital heart defects or pericardial disease.

But here’s the rub: many traditional medications have side effects like vomiting, diarrhea, or lethargy, especially with long-term use. This has pet parents looking for ways to complement or even reduce their reliance on prescription medications. Enter CBD oil!

Why CBD Oil? Understanding Its Potential for Canine Heart Health

CBD, or cannabidiol, is a compound found in the hemp plant that’s been getting a lot of attention for its therapeutic effects on humans and animals alike. And unlike THC, CBD isn’t psychoactive, so it won’t get a dog “high.” Listed below are the potential heart health benefits of CBD.

Anti-Inflammatory Properties: Inflammation is a major contributor to heart disease. Studies show that “CBD, CBG, and CBD+THC combination exert a predominantly anti-inflammatory effect in vivo, potentially reducing inflammation in blood vessels,” (Henshaw, F., et al., 2021), which eases the strain on the heart.

Blood Pressure Benefits: High blood pressure stresses the heart and blood vessels. Some studies suggest that CBD helps lower blood pressure, taking some of the load off a struggling heart (Kossakowski, R., et al., 2019; Kumrić, M., et al., 2022).

Anxiety Reduction: Stress and anxiety aren’t great for the heart (human or dog). CBD’s calming effects help lower stress-induced heart rate increases, making it easier for dogs to relax. A study on the haemodynamic effects of cannabidiol showed that “CBD reduces blood pressure and heart rate in stressful conditions and increases cerebral blood flow in mouse models of stroke,” (Sultan, S., et al., 2017).

Antioxidant Effects: CBD is a powerful antioxidant, which means it helps protect cells—including heart cells—from damage. This antioxidant power supports the immune system and overall heart health. A systematic review of non-clinical studies concluded that “CBD protects against cardiac injuries mainly through its anti-oxidant, anti-inflammatory, and anti-apoptotic effects,” (Shayesteh, M., et al., 2019).

Pain Relief: Dogs with heart disease sometimes have concurrent pain issues (think arthritis). CBD provides relief without the side effects of many traditional pain medications.

Weight Management: Keeping a healthy weight is crucial for dogs with heart disease. Preliminary research suggests CBD plays a role in managing weight by affecting appetite and metabolism.

Using CBD for Dogs with Heart Disease

Before giving CBD oil to a dog, especially for a serious condition like heart disease, there are a few essential things to keep in mind.

Consult A Veterinarian: Always consult the dog’s veterinarian before introducing CBD, particularly if a dog is already on other medications. CBD interacts with some drugs, so it’s important to get the dosage right with a professional’s help.

Choosing the Right Product: Go for full-spectrum CBD oils made specifically for dogs. The CBD oil must be third-party tested for quality and purity. Avoid anything with THC, as it’s toxic to dogs. Look for the Certificate of Analysis (COA).

Start Slow: CBD oil for dogs comes in different strengths. Start with a low dose and slowly increase it, monitoring the dog’s response. Dosing depends on the dog’s weight and health, so a gradual approach is often best.

CBD into a Holistic Plan for Dog Heart Health

Using CBD alone isn’t the silver bullet. Think of it more like the best supporting actor in the heart health scene. To truly maximize a dog’s quality of life and heart health, a holistic approach is best:

Heart-Healthy Diet: Make sure a dog’s diet is balanced with essential amino acids (like taurine) from sources like organ meats and fatty fish. Consider adding omega-3 fatty acids from fish oil, which support heart function and reduce inflammation.

Maintain a Healthy Weight: Obesity imposes additional stress on a dog’s cardiovascular system. Maintain a dog’s activity level through low-impact exercises suited to their capabilities.

Regular Vet Checkups: These are critical for monitoring heart function and catching any changes early. Many vets now work in tandem with holistic vets to offer complementary care options, including natural supplements like CBD.

Minimize Stress: Use calming techniques, like gentle massage or aromatherapy, and create a serene environment. CBD is a potential part of this effort, helping to reduce a dog’s anxiety levels, particularly in high-stress situations.

Holistic Supplements: Adding in CoQ10, medicinal mushrooms, or brown rice offers cardiovascular support. These natural remedies have antioxidant properties that are especially beneficial for dogs with heart disease.

How to Find High-Quality CBD Oil for A Dog

Finding quality CBD oil feels like searching for the holy grail, especially with so many options on the market. Listed below are what to look for.

Pet-Specific Formulas: Opt for CBD oils made specifically for dogs. The right product is free from THC, with dosages and formulations that account for a dog’s system.

Third-Party Lab Testing: Make sure the CBD oil has been independently tested for potency and purity.

Organic Hemp Source: High-quality CBD starts with high-quality hemp. Organically grown hemp ensures no pesticides or toxins sneak into the pet’s system.

Full-Spectrum vs. Isolate: Full-spectrum CBD oil includes other beneficial compounds from the hemp plant taking advantage of the entourage effect, while isolates are pure CBD. Both have their perks, so discuss with the dog’s veterinarian which is best for the dog.

Pet Parents’ Guide: CBD Dosage Tips and Tricks

Starting CBD for a dog feels like diving into a science experiment, but there’s no need to stress. Getting the dosage right for a furry friend is simpler than it sounds, and a few key guidelines make all the difference. Some tips to keep dosing simple are listed below.

Calculate Dosage Based on The Dog’s Weight

A good starting point when dosing CBD oil for dogs with heart disease (or any health issue) is to factor in the dog’s weight. Most pet-specific CBD products come with dosage guidelines to make this easier. For example, a typical starting point is 0.1-0.2 mg of CBD per pound of body weight per day.

Start Low, Then Gradually Adjust

One of the biggest keys to successfully dosing CBD is the “start low, go slow” method. This approach helps find the right amount for the dog without overdoing it.

Why Start Small?

Starting small and increasing gradually allows pet parents to see how their dog responds to CBD, which varies based on factors like age, metabolism, and the severity of their condition. A smaller dose allows the dog’s body to adjust to the new supplement and reduces the chances of any mild side effects.

Use Consistently for Best Results

Consistency is crucial for CBD’s effectiveness. JCBD is most beneficial when used consistently over time.

Why Daily Dosing Works

The benefits of CBD for dogs with heart disease or other chronic issues typically build over time as it accumulates in the body’s endocannabinoid system. For best results, administer CBD daily and ideally at the same time each day. Sticking to a regular schedule not only makes the supplement more effective but also simplifies the routine for pet parents and their dogs.

Be Patient – Results Take Time!

One of the most important things to remember with CBD oil is that it’s not a “quick fix.” CBD works best with regular use and some patience, especially when targeting something as complex as cardiovascular health.

What to Expect with CBD for Heart Health

Unlike certain medications that show effects right away, CBD takes anywhere from a few days to a couple of weeks to build up in the dog’s system. So, if a pet parent is using CBD oil to support heart health by helping to lower blood pressure, reduce inflammation in blood vessels, or relieve anxiety, expect gradual changes rather than overnight results.

Keep The Vet in the Loop

Adding CBD to a dog’s regimen is an exciting step, especially with heart health benefits like reducing inflammation, lowering blood pressure, and providing pain relief. But remember: the dog’s veterinarian is the best ally here.

Why Involve The Veterinarian?

If a dog is already taking medications for heart disease, like ACE inhibitors, diuretics, or beta-blockers, CBD interacts with them. The vet guides pet parents on how to safely add CBD to their dog’s routine, whether it means adjusting doses or monitoring more closely. Vets also offer additional advice on complementary supplements, dietary adjustments, and other heart-friendly changes.
