My dog has heart failure and ascites. What to expect at end of life?
These decisions are certainly not easy to make and I'm sorry that you and Pepper are going through this. While I can't examine Pepper to speak to his current state of respiratory distress or discomfort, anytime ascites and respiratory changes consistent with heart failure are present, the animal is generally uncomfortable. With heart failure, animals accumulate fluid in and around the lungs and do not appropriately perfuse oxygenated blood, causing a weakened state with difficulty breathing.
In cases of heart failure, I would recommend either trying appropriate diuretics and other medications (possibly enalapril/benazapril and pimobendan, as indicated) or euthanizing. Without reducing the fluid in the chest and improving heart contractility to allow for better oxygenation, animals have a diminished quality of life. Closely monitor Pepper for more effort in his breathing, coughing, inappetance and lethargy. I'm sorry you're going through this and I hope this helps.
