Management Guidelines by Stage

Initial Stage (Mild)

• What is the condition? This is a stage where structural changes in the heart are just beginning or are very minor. The heart is still functioning adequately on its own, and there are no specific symptoms.
• What is the prognosis? It is highly likely that the dog will live without any significant problems for a long period. The prognosis is generally good, and it may take several years for actual heart problems to manifest.
• How should it be managed? Medication is not required at this stage. However, it's important to recognize the presence of heart disease and manage it consistently.
  • Regular Check-ups: Visiting the vet every 6-12 months to monitor any changes in heart size or function is crucial.
  • Weight Management: Obesity puts extra strain on the heart, so maintaining a healthy weight is very important.
  • Dietary Management: Provide a balanced diet and avoid salty human foods or excessive treats.

Moderate & Severe Stage

• What is the condition? The heart disease has progressed, and there are clear structural changes, such as a noticeably enlarged heart. There may still be no outward symptoms, but the heart is already under strain.
• What is the prognosis? From this point, the disease can progress more rapidly. This group is at a high risk of developing symptoms of heart failure, such as coughing or difficulty breathing, in the near future.
• How should it be managed? This is a critical point for active veterinary intervention. Treatment should not be delayed just because there are no symptoms.
  • Medical Management: Medication to help the heart work more efficiently and delay the onset of severe symptoms is strongly recommended. Consistent administration of prescribed drugs is key.
  • Dietary Management: A heart-healthy diet that is lower in sodium can be beneficial.
  • Behavioral & Environmental Management: Regularly monitoring and recording the resting respiratory rate (breaths per minute) is very important. A significant increase could be a sign of heart strain and requires immediate veterinary consultation. Avoid strenuous exercise and exciting situations.

End-Stage

• What is the condition? The heart disease is advanced, leading to symptoms of congestive heart failure like coughing, difficulty breathing, and exercise intolerance, or it is a severe stage that does not respond well to standard treatments.
• How should it be managed? The goal of treatment at this stage is to alleviate uncomfortable symptoms and improve the quality of life as much as possible.
  • Medical Management: A combination of drugs will be used to manage fluid in the lungs and support heart function. Intensive management and regular monitoring by a veterinarian are essential.
  • Dietary Management: Special care must be taken to prevent loss of appetite or weight. Efforts to maintain appetite, such as warming food or mixing in favorites, are necessary. Adequate calorie and protein intake is vital.
  • Behavioral & Environmental Management: Monitoring the resting respiratory rate remains a key indicator of the dog's condition. Create a comfortable, quiet environment to minimize stress. Light walks are acceptable as long as they don't cause distress.
