Yes – Heartworm is transmitted through mosquitoes, which are not only a danger if your pet lives outdoors, they can travel inside your home too. Remember, it only takes one mosquito to infect your pet.
After the mosquito bites, it infects the dog with the larvae stage of the worm, also known as the microfilariae. This larvae goes through several cycles as it travels through the dogs system, until finally reaching the heart and lungs and the adjacent vessels. Early signs of heartworm are; coughing, weight loss, low energy levels, and difficulty breathing. This causes congestive heart failure and eventually, death.
