By | May 1, 2015

With summers just around the corner, pets may need intensive care.  The humid and warm weather of summers induces parasitic as well as heartworm infestation in canines. According to the studies of Companion Animal Parasite Council (CAPC), heartworm infections are prevalent in all 50 states of the U.S. Pets of Southeastern states are affected the most by this infection. To prevent heartworm infestation, veterinarians recommend using heartwormers for dogs throughout the year.

What is Heartworms?

Heartworm is unquestionably a dangerous disease that may be found in practically any corner of the world. Dirofilaria immitis worms, which are cylindrical, slender, and foot-long parasites, cause it. They live in the heart, lungs, and blood arteries of the infected animal, causing abrupt heart failure, lung illness, and serious damage to many areas of the afflicted animal. Heartworm infection can be seen in dogs, cats, ferrets, and other animal species including wolves and foxes, as well as humans on rare occasions. Because of their proximity to non-rural regions, wild animals such as wolves are thought to be key carriers of the disease.

Let’s catch some important details regarding heartworms and their preventive options that could protect your furry friends this summer!

Why are heartwormers necessary in summers?

Heartworms are transmitted to dogs through a bite of the mosquito that has already been to an infected host. The temperate and humid atmosphere of summers creates a prime breeding ground for mosquitoes that spread the heartworm larvae from infected dogs. Around late February and early March, female heartworms release massive amounts of larvae which are then carried to another host by mosquitoes. If your poodle is not on a continuous heartworm preventive, they may have to face some serious health issues in this season.

Summers have the maximum possibilities of the larva transfer through mosquitoes. To keep your furry friend away from this lethal infection, vets recommend treating them with heartwormers for dogs every month. Before starting any preventive treatment, it is necessary to get your canine checked up for heartworm infection. It is advisable to start with these treatments only if your pooch has no trace of heartworms in them.

Symptoms of Heartworm Infection

In the early stages of the infection, many dogs show very few or no symptoms at all. Symptoms are more likely to emerge as the illness progresses. Clinical indications in heavily infected canines or animals afflicted with various ailments are common. The following is a list of the most common symptoms of heartworm infection:

  • Soft and dry cough
  • Lethargy
  • Loss of appetite

  • Bulging chest
  • Difficult or rapid breathing
  • Allergic reactions
  • Collapse or unconsciousness

Other signs and symptoms of heartworm disease include nosebleeds, pneumonia, excessive sleep, elevated blood pressure, and so on. These parasites can cause blindness or seizures if they reach other organs such as the brain or eyes. These symptoms are uncommon, but they do occur in some situations.

How to shield your furry friends from Heartworm infection?

The simplest and safest way to protect your pawed friends from this lethal infection and its diseases is to keep them on heart wormers all around the year, even in cold weather.
