Clayton Perlman: Common Canine Heartworm Symptoms

Clayton Perlman has always been an avid dog lover and he is dedicated the care and wellbeing of canine companions. Heartworm disease in dogs is a silent killer and is commonly overlooked until it is too late. This preventable condition starts with a mosquito bite and ends with either a long and expensive treatment or death. Additionally, Clayton Perlman explains, heartworm symptoms may not appear for months and shares some common signs that a dog may have heartworms.



The parasites make their way to the lungs and start multiplying in the lungs and surrounding veins. Coughing may be most noticeable after exercise and may end with fainting. Even light exercise can cause fainting.


Rapid or Labored Breathing

Along with coughing, breathing problems can occur when the worms inhabit the lungs and surrounding veins. Fluid can also build around the blood vessels in the lungs, making it difficult for your dog's lungs to oxygenate blood.


Inactivity and/or Lethargy

If your dog suddenly seems more tired than usual, does not want to go outside, or avoids physical activity completely, he or she may have heartworms. Dogs with a heartworm infection are weakened and find it difficult to be active even when performing small tasks.


Weight Loss and/or Loss of Appetite

Even minor physical activities, such as eating, can become difficult and exhausting chores in canines with heartworm infections.



Large numbers of heartworms invade the heart and cause blockage of blood flow (known as Caval or Vena Cava Syndrome). Collapse is usually accompanied by shock and red blood cell destruction. When a heartworm infection is this advanced, death usually follows within days.
