Do Dogs And Cats Get Bitten By Mosquitoes Like We Humans Do?

I’m pretty sure we don’t all love those pesky mosquitoes. The itchy bites and buzz of mosquitoes when they fly near us are some of the most annoying. Humanity has been and will continue to strive in the process of eliminating mosquitoes from life, not only because their bites are annoying but also because they carry the risk of transmitting dangerous diseases to humans. dengue fever for example. Have you ever wondered if mosquitoes bite dogs and cats? Yes, mosquitoes bite dogs and cats just like us. Let’s take a closer look with Fetch.

Heartworm disease in dogs & cats

Mosquitoes carry heartworm parasites – a parasite that enters the pet’s vascular system and eventually stays in the target organs of the heart and lungs, developing into adults and reproducing there. Heartworms in dogs and cats have a few different symptoms & effects that are further explored below.


Dogs are bitten by mosquitoes and transmit heartworm larvae into the bloodstream. Here are 5 signs your dog has a heartworm infection:

1. Persistent cough

Unlike a common cough or kennel cough, where a dog coughs strongly and sporadically, a heartworm cough is a dry, persistent cough. In the early stages, even light exercise causes a dog to cough, as the heartworms are moving into the lungs creating blockages and irritation.

2. Lethargy

If your dog suddenly doesn’t want to go for a walk or do nothing at all, this could be a sign of heartworms. As the condition worsens, any activity becomes overwhelming for the baby.

3.Weight loss

When the heartworm condition becomes severe, the dog will seem to have no energy to perform even the simplest activities. Even eating becomes too difficult and thus leads to rapid weight loss.

Mid-stage symptoms of heartworm disease:

As heartworms mature, they colonize the host’s lungs and veins, causing severe obstruction and leading to the following symptoms:

4. Difficulty breathing

Along with the persistent cough, other symptoms similar to those of asthma occur in dogs. Fluid can also build up in the blood vessels around the lungs, making it harder for the lungs to get oxygen from the blood.

5. Bigger ribs

As fluid continues to build up and fill the lungs with fluid, the dog’s chest will grow larger. The ribs also appear to be more visible and larger due to the dog’s weight loss. This condition occurs as a result of the body’s fluid accumulation in response to the presence of the parasite.
Once the heartworm has fully matured in the dog’s heart and lungs, the dog will show extremely clear symptoms of heartworm disease, which unfortunately will carry long-term consequences for the dog’s health.

Late stage symptoms of heartworm disease

As with the early stages of heartworm disease, you’ll find your dog doesn’t want to eat, has a dry cough, and is lethargic. These symptoms will become more severe in the late stages, and complications of the disease begin to appear.


Cats are just as likely to be bitten by mosquitoes and transmit heartworm disease as dogs. But because cats are not the same host as dogs, the symptoms are not as obvious and the condition is not as severe as in dogs.
The most common clinical symptoms encountered when cats have heartworm infections include: – intermittent vomiting (sometimes with food or blood mixed up)

  • Diarrhea
  • Shortness of breath and shortness of breath
  • Dry cough
    (The symptoms above are easily confused with asthma or respiratory diseases in cats)
  • Not eat
  • Lethargy and weight loss

In most cases, cats will survive for a long time after being infected with heartworms, before dying from some disorder due to the disease. In the case of an acute illness, the cat will die suddenly.

Unfortunately, heartworm disease in cats – unlike dogs – cannot be cured. The drugs used to treat heartworms in dogs are too toxic and can kill cats.

How to protect pets from mosquitoes? Can the owner use mosquito incense or insect spray?

To prevent mosquitoes from pets:

It doesn’t matter what type of heartworm product and treatment you and your veterinarian choose to protect your pet at home, as long as your baby is used for the right course and for the duration to be protected from mosquitoes.

clean stagnant water ponds

Mosquitoes breed in puddles of standing water, including puddles, ponds, outdoor dog pots, and birdbaths. Any place where rain or irrigation water collects can be a breeding ground for mosquitoes. If your home has items like the ones listed above, be aware that these are mosquito breeding grounds and your pet will be more likely to be bitten by mosquitoes near them.
You may want to consider minimizing the amount of water in your home.

There are some plants that have the effect of repelling insects naturally, planting a few pots in the house will help protect your pet from mosquitoes better.
Well-known plants for repelling mosquitoes include lavender, catnip, basil, lemon basil, mint, and rosemary.
