Dilated cardiomyopathy (DCM) is a relatively common condition which affects the heart of a dog, and can be life-threatening. Knowing how long a dog can live with the condition is important for pet owners who want to provide the best possible care for their furry friend. The prognosis for dogs with DCM varies depending on the severity of the disease and the type of treatment the pet is given. In this blog post, we will discuss the possible life expectancy of a dog with dilated cardiomyopathy, as well as what can be done to help prolong your pet’s life. We will also review the warning signs of DCM and the importance of regular veterinary check-ups in order to catch the disease early.
My dog suddenly seemed to develop dilated cardiomyopathy. Can this disease develop that quickly?
Although the clinical signs of dilated cardiomyopathy may appear suddenly, the disease has actually been slowly and subtly progressing. In just a few hours, some dogs can develop severe congestive heart failure (CHF). The initial symptoms may include rapid, heavy breathing, a blue tongue, excessive drooling, or collapse.
The Anatomy of Dilated Cardiomyopathy in Dogs
Despite the fact that the condition has at least five distinct symptoms (more on this below), these problems typically don’t surface until the disease has advanced.
Because of this, a dog with dilated cardiomyopathy has a relatively short life expectancy. Dilated Cardiomyopathy is a disease of the heart muscle.
It results in the heart’s chambers dilating (widening), which impairs performance.
The disease typically affects both sides of the heart, but some dog breeds have only experienced one side of the heart being affected.
Because there is simply insufficient pressure to pump blood through the vascular system, the heart becomes weaker over time.
Blood pools in the veins when the heart isn’t functioning properly. At this point, a few things can happen:

FAQ
What is the life expectancy of a dog with dilated cardiomyopathy?
Long term prognosis for DCM varies considerably. Sadly, within six months of diagnosis, the majority of dogs with congestive heart failure symptoms pass away from the condition. In the worst circumstances, some dogs may only live a few weeks to months. Occasionally, dogs may do well clinically for 1-2 years.
What are the stages of DCM in dogs?
DCM typically has two phases: 1) An occult phase, when the disease is present but the dogs don’t show any symptoms. This phase can last months to years. 2) An overt clinical phase, when clinical signs develop.
How long can a dog live with an enlarged heart on medication?
Most dogs with DCM eventually pass away from the condition despite therapy and diligent care. Based on the disease’s course at the time of diagnosis, your veterinarian will give you advice about your pet’s prognosis. Dogs with this condition typically have 6 to 24 months to live.
How quickly does DCM progress?
Although the clinical signs of dilated cardiomyopathy may appear suddenly, the disease has actually been slowly and subtly progressing. In just a few hours, some dogs can develop severe congestive heart failure (CHF). The initial symptoms may include rapid, heavy breathing, a blue tongue, excessive drooling, or collapse.
