Heartworm Prevention for Dogs

Heartworm disease is a serious and potentially fatal disease in dogs caused by infection with Dirofilaria immitis, a parasitic worm. Heartworms are spread through the bite of an infected mosquito. The mosquito takes a blood meal from an infected dog and then bites another dog, transferring the larvae of the heartworm to the new dog. The larvae mature in the dog's bloodstream over a period of several months and eventually become adult heartworms, which live in the heart, lungs, and blood vessels.

Heartworm disease can cause a variety of symptoms in dogs, including coughing, difficulty breathing, weight loss, and exercise intolerance. In severe cases, heartworm disease can lead to heart failure, shock, and death.

There is no cure for heartworm disease in dogs. Treatment involves a series of injections that kill the adult heartworms. This treatment is expensive and can be risky, and it may not be successful in all cases. The best way to prevent heartworm disease is to give your dog a monthly heartworm preventive medication.

There are a variety of heartworm preventive medications available, both oral and topical. Some medications also protect against other parasites, such as fleas and ticks. Talk to your veterinarian about which heartworm preventive medication is best for your dog.

It is important to start giving your dog a heartworm preventive medication before they are exposed to mosquitoes. This is because it takes several months for the heartworms to mature and cause disease. Most veterinarians recommend starting heartworm prevention in puppies as young as 6 weeks old.

Even if you live in an area where mosquitoes are not common, it is still important to give your dog a heartworm preventive medication. Mosquitoes can travel long distances, so even if you live in a cold climate, your dog could be exposed to an infected mosquito.
