Congestive Heart Failure in Dogs

Congenital Heart Disease in Dogs

Your beloved pet can have heart problems just like you. Know the symptoms so you can get your companion the help she needs.

Heart disease may lead to congestive heart failure. That's when your dog's heart has trouble pumping blood to the rest of its body.

Heart disease can affect one side of the heart or sometimes both sides. It can progress slowly and may take years to spot.

 

Causes

Congenital means that the dog was born with a heart defect. But old age, injury, and infection can exacerbate it. Diet and exercise play roles too.

Symptoms

Take notice of these early symptoms of heart problems:

More symptoms may develop, as the disease gets worse, including:

  • A swollen belly from fluid buildup in (called ascites)
  • Fainting because of blocked blood flow to the brain
  • Change in tongue or gum color to bluish gray because of poor oxygen flow
  • Weight loss as your dog loses her ability to store healthy fat

Getting a Diagnosis

Your vet will want to know any symptoms you've noticed. He or she will want to know what she eats, what medications and supplements she may be taking, and if she is current on heartworm protection.

The vet will listen to your dog's chest and may want to run some tests, including:

  • A blood and urine test to check for any other problems that could be affecting your dog's heart.
  • Chest X-rays. These use radiation in low doses to make images of your dog's internal organs.
  • An EKG. This test measures electrical signals from your dog's heart and tells how fast it's beating and if that rhythm is healthy.
  • An ultrasound. Ultrasound uses sound waves to look at the size, shape, and movement of the heart.
  • Heartworm antigen test. Your vet will take blood from your dog to test it for heartworms.
  • Holter monitor. This is taped to your dog’s chest and worn for 24-48 hours to capture heart rhythms and rate.

Treatment

Your dog's treatment depends on what specific heart problem she has and what may be causing it.

Your vet may recommend one or more of the following:

  • Medications to help the heart work and correct irregular heartbeats
  • Medications to slow fluid build-up in the lungs
  • Surgery to correct a torn valve or to insert a pacemaker to correct the heart beat
  • A commercial or prescription low-salt diet to help decrease fluid build-up in your dog's body
  • Limited activity or exercise to manage weight without putting too much strain on your dog's heart

Your vet may also recommend supplements. Dogs with congestive heart failure may benefit from vitamin B supplements, taurine (an amino acid that supports brain development), or carnitine (an amino acid that helps turn fat into energy). Antioxidants like Coenzyme Q and vitamin E may also help.

Medication can also clear heartworms or bacterial infections if they're caught early enough.

What to Expect

Make sure to bring your dog for regular visits with your vet and stick with your treatment plan. Unchecked heart problems can make things harder on your dog and even shorten her life. With the right treatments, care, and monitoring, your dog can live a long, comfortable life.
