How Can I Help Manage My Dogs Heart Disease?

A diagnosis of heart disease in a dog can be difficult, but with the right lifestyle adjustments, many dogs can continue to lead happy, comfortable lives. Managing heart disease requires a combination of veterinary care, medication, a heart-healthy diet, and lifestyle changes tailored to each dog's specific needs. Here’s a comprehensive guide to the best lifestyle adjustments for dogs with heart disease, covering exercise, stress reduction, environmental modifications, dietary tips, and essential veterinary monitoring.

1. Exercise Modifications

Exercise is generally beneficial for dogs, but with heart disease, their activity needs to change. Too much exertion can strain a dog’s heart, so it’s important to find the right balance to keep your dog active but safe.

• Opt for Low-Impact Activities: Gentle activities, like short, controlled walks, are preferable to intense runs or long hikes. These activities provide mental stimulation and cardiovascular benefits without overburdening the heart. Keep walks brief, and monitor your dog’s breathing, energy levels, and overall comfort during and after exercise. Some dogs might enjoy light play indoors or in a shaded yard, which also allows you to monitor their energy levels closely.
• Follow a Consistent Routine: Having a regular schedule for exercise helps maintain a steady heart rate. Irregular exercise or sudden bursts of activity can increase heart rate sharply and may cause stress, which is particularly challenging for dogs with heart conditions. A routine that incorporates gentle, predictable activities will help keep their heart rate stable and avoid sudden changes that could strain their heart.
• Watch for Signs of Fatigue: Dogs with heart disease may tire more easily. Signs of fatigue include panting, coughing, or reluctance to continue. These may indicate overexertion, and it's essential to let your dog rest if any of these signs appear. If you notice these symptoms frequently, consult your vet, who can help you fine-tune the type and amount of exercise that’s safe for your dog’s stage of heart disease.

2. Dietary Adjustments

Nutrition is a critical component of heart disease management. A tailored diet can reduce the heart's workload and support overall health, helping manage symptoms and improve quality of life.

• Low-Sodium Diet: Sodium can cause fluid retention, leading to higher blood pressure and worsening heart disease symptoms. A low-sodium diet can alleviate some of the pressure on the heart. Ask your vet if a low-sodium diet would suit your dog. 
• Maintain a Healthy Weight: Excess weight increases the heart’s workload. Keeping your dog at a healthy weight reduces stress on their heart and supports long-term health. Work with your veterinarian on a weight management plan, choosing nutrient-dense foods that provide energy without excess calories. Your vet can also recommend treats or food portions that support weight control while meeting your dog’s dietary needs.
• Consider Heart-Healthy Supplements: Omega-3 fatty acids from fish oil can help reduce inflammation and support cardiovascular health. Always consult your vet before introducing any supplements, as they can guide you on dosage and any potential interactions with medications.

3. Stress Reduction Techniques

Reducing stress is essential for dogs with heart disease, as stress can exacerbate symptoms and negatively impact heart health. Here are some techniques for creating a calm, low-stress environment:

• Create a Quiet Space: Designate a quiet, comfortable resting area in your home where your dog can relax. This space should be away from loud noises, foot traffic, or high activity areas. Providing a soft bed or a familiar blanket can make this area even more inviting and comforting.
• Minimise Excitement: Many dogs become overly excited in certain situations, like when guests arrive or during mealtime. Excitement can elevate heart rate and may be taxing for a dog with heart disease. Setting boundaries, such as keeping the dog in a quiet room during stimulating events, can help. You can also redirect their focus with a favourite toy or soothing chew to keep them calm.
• Use Gentle Handling: Dogs with heart disease may be more sensitive, so always approach them gently, especially if they’re resting. Avoid sudden movements or loud noises that could startle them, as this could elevate their heart rate. If you have children or other pets, consider setting guidelines to ensure gentle handling of your dog.

4. Environmental Adjustments

Optimising your dog’s surroundings can reduce physical strain and create a more supportive environment for their needs.

• Add Non-Slip Flooring: Dogs with reduced stamina or limited mobility may have difficulty maintaining balance on slick floors, which can cause them to slip and raise their heart rate. Consider adding non-slip mats or rugs in areas where your dog spends most of their time.
• Limit Stairs: Climbing stairs can be strenuous, especially for dogs with advanced heart disease. Restrict access to stairs, or, if necessary, use ramps for easier mobility. Limiting stair access will prevent unnecessary exertion and protect their heart.
• Control the Temperature: Dogs with heart disease are more susceptible to the effects of heat, which can worsen symptoms. Keep your dog’s environment cool and comfortable, especially during warmer months. Fans, air conditioning, or a cool mat can help keep your dog comfortable, particularly in breeds that are prone to overheating.

5. Medication Management

Medication is often a key part of heart disease management. Following your veterinarian’s medication schedule is crucial to stabilising symptoms and maintaining health.

• Stick to a Schedule: Administering medication at the same time each day helps stabilise your dog’s condition and avoid fluctuations in their symptoms. Use reminders, alarms, or a daily medication chart to track dosages and timing, ensuring you don’t miss any doses.
• Monitor for Side Effects: Some medications can cause adverse reactions or behavioural changes. Watch for symptoms like vomiting, lethargy, or any other unusual signs after starting a new medication. Contact your vet immediately if you notice any side effects, as adjustments to medication may be needed.
• Regular Check-Ups: Heart disease can progress over time, so regular veterinary visits are essential. These visits allow your vet to monitor heart function, adjust medications if needed, and track overall health.

6. Regular Vet Visits and Health Monitoring

Frequent check-ups are vital for effective heart disease management, allowing vets to monitor progress and adjust treatment as needed.

• Heart Function Monitoring: Your vet may recommend periodic echocardiograms, X-rays, or blood tests to monitor heart function and evaluate how well the treatment plan is working. These assessments are essential for catching any early signs of disease progression and making timely adjustments.
• Monitor Breathing Rate at Home: Tracking your dog’s resting respiratory rate at home can be a valuable tool. Count their breaths per minute while they are asleep or resting; an increase could indicate fluid buildup, a common complication. Your vet can advise on normal breathing rates and what to do if they increase.
• Keep a Journal of Appetite and Behaviour: Changes in appetite, energy level, or general demeanour could signal a shift in your dog’s condition. Keeping a daily log can help you spot patterns or concerns early and provide valuable information to your vet during check-ups.

In Summary 

Caring for a dog with heart disease can be challenging, but with the right approach, you can help them enjoy a happy, fulfilling life. This guide highlights the importance of working closely with your vet to create a personalised care plan, including tailored nutrition and proper management strategies. By staying proactive and informed, you can make a positive difference in your dog’s health and well-being.
