When a dog dies from congestive heart failure (CHF), it's often a progression where the heart can't pump effectively, leading to fluid buildup (edema) in the lungs (pulmonary edema) or abdomen (ascites), causing severe breathing distress, weakness, collapse, and eventually, organ shutdown due to oxygen deprivation, sometimes culminating in a rapid cardiac arrest, where the heart stops beating and breathing ceases. The dog effectively suffocates or suffers multi-organ failure from the inability to circulate oxygenated blood.
