Congestive heart failure
in dogs is a condition when the heart is unable to adequate circulates blood
necessary to meet the needs of the body. The result is a weakened heart muscle.
Eventually, the health of the lungs, liver, kidneys, and other organs are
impaired which can result in the failing of multiple organs. In this instance,
dogs can go years or months with a diseased heart and not show any signs.
When the overall failure does occur, the onset
is sudden and often unexpected. It might, for instance, show after strenuous
exercise when the heart is unable to provide adequate circulation. The early
signals that your English Labrador
has congestive heart failure are a major decrease in the level of activity,
being tired easily, and intermittent coughing. This coughing might occur during
exertion. This coughing might also take place approximately two hours after the
dog has gone to sleep. They might also restlessly pace before going to sleep
rather than settling down quickly. As the congestive heart failure in dogs
continues to worsen, additional signs will be a reduction in appetite, swelling
of the abdomen, significant weight loss, and rapid breathing.
Congestive heart failure in dogs is more common with small breeds due to chronicvalvular disease but in large dogs is commonly associated with cardiomyopathy. Some causes include heartworm, cardiomyopathy, degeneration of the heart valves, inflammation of the pericardium, congenital heart defects, or arrhythmia.
Treatment can cure some forms of the heart
disease so long as the treatment is initiated prior to damage to the heart. It
involves restricting the amount of exercise, feeding your dog a low-salt diet,
and administering appropriate medications which will prevent cardiac
arrhythmias and increase the heart function. Many commercial dog foods contain
excessive salt amounts. As such, your veterinarian is able to prescribe
suitable diets. If the dog is only showing mild symptoms, a change in diet
might be the only thing required. If your dog is showing signs of rapid
breathing, tiring easily, or couching, then they should not be allowed to
engage in activities and exercise which would cause this. At home treatment
includes providing a stress free environment for your English Labrador and allowing your dog to practice an activity
level with which he is comfortable. You should monitor any signs of fainting or
heavy breathing.
There are a few ways in
which you can prevent congestive heart failure in dogs. The first is to ensure
that the English Labrador remains on heart worm
preventative medications. This will eliminate parasites which might otherwise
cause further degeneration of the heart. It is also important to promptly treat
any viruses or infections to reduce the odds of pericardium. Most of the time
congestive heart failure in dogs is caused by genetic predispositions to health
issues not by environment. Dogs which have a heart defect should not be bred.
If you do breed dogs it is your responsibility to test for these problems and
cease breeding dogs which show signs.
