October 20, 2010 | Dog Health | Leave a Comment |

Dog is known to be man’s best friend. As such, people often take great care of their dogs and sometimes treat them like their own children. Much like humans, dogs also suffer from a wide array of illnesses and health problems that can sometimes be life threatening. Among the common health problems dogs face when they reach their middle age is dealing with an enlarged heart.

What Causes An Enlarged Heart In Dogs?

Despite being one of the most common causes of heart failures, there is no specific cause of a dog’s enlarged heart.

However, research has shown that the typical parvovirus, or any group of viruses that contains DNA can cause the enlargement of the heart. Other possible causes that research has shown include taurine deficiencies as well as adriamycin as having some effect that is related to the enlarged heart in dogs.

Signs of Heart Enlargement in Dogs

Unfortunately a dog with an enlarged heart does not really show a lot of symptoms that can truly be noted ahead of time. Below are some of the usual signs found in dogs with enlarged hearts that should serve as warning to owners:

  • Coughing
  • Heart failure
  • Difficulty in breathing
  • Collapsed abdomen
  • Tiredness

Among the signs cited above, cough and heart failure are deemed to be the two most prominent signs.

Difficulty in breathing may be harder to detect since dogs are often always on the move. Upon the onset of the said signs, these can be diagnosed further by visiting a vet and performing some tests such as electrocardiography, X-rays and other means to further detect the problem.

Treatment for Dog with Enlarged Heart

So far, there is no cure that has been developed to address an enlarged heart in dogs. However, some treatments may be performed to prolong the life of the dog, and interactions with the drugs may also vary.
