As more pet owners face the challenge of caring for dogs diagnosed with heart disease, veterinary experts emphasize that scientific daily care is key to slowing disease progression and improving quality of life. From dietary adjustments to controlled exercise, here are critical practices every caregiver should adopt.
Low-Salt Diet: A Foundation for Heart Health
Dogs with heart disease are particularly sensitive to sodium, as excess salt can trigger blood pressure fluctuations and exacerbate heart strain. Veterinary nutritionists recommend switching to prescription low-sodium dog food or preparing homemade meals with vet-approved, salt-free ingredients. "Avoid table scraps, processed treats, or even small amounts of salty human food—these can undo weeks of careful diet management," warns Dr. Emily Carter, a board-certified veterinary cardiologist.
Controlled Water Intake to Reduce Cardiac Burden
While hydration is vital, overconsumption of water increases blood volume, putting extra pressure on the heart. Experts advise following a general guideline: limit water intake to 40 milliliters per kilogram of the dog’s body weight daily. "Monitor water bowls closely, especially for dogs prone to drinking excessively," Dr. Carter adds. "Adjust amounts based on your vet’s advice, as activity level or medication may require slight modifications."
Gentle Exercise: Avoid Agitation, Prioritize Consistency
Intense play, sudden runs, or overexcitement can spike a dog’s heart rate dangerously. Instead, moderate walking is the gold standard for exercise. "Short, frequent walks—such as 10-15 minutes twice a day—are better than long, strenuous outings," says Dr. Mark Taylor, a general practice veterinarian. "Always observe your dog’s behavior: if they pant heavily, slow down, or show signs of fatigue, stop immediately and consult your vet to adjust the routine."
Regular Respiratory Monitoring: Catch Abnormalities Early
A dog’s breathing rate is a reliable indicator of heart function. Owners should check their pet’s respiratory rate at rest (e.g., while sleeping) and record the number of breaths per minute. "Normal rates range from 10-30 breaths per minute for most adult dogs," explains Dr. Carter. "If you notice a consistent increase—especially over 30 breaths per minute—or labored breathing, contact your vet immediately. This could signal fluid buildup in the lungs, a common complication of heart disease."
Targeted Medication: Support Myocardial Health
Two key products are widely recommended for heart disease management:
By integrating these daily care practices, pet owners can help their dogs live longer, more comfortable lives with heart disease. The second part of this series will focus on long-term lifestyle habits and safety precautions to further support cardiac health.
