Treat Heartworms in Dogs: A Comprehensive Guide

Heartworm infection is a serious and potentially fatal disease that can affect dogs of all ages, breeds, and sizes. It is caused by parasitic worms that live in the heart and lungs of infected animals. Heartworms can cause a variety of symptoms, including coughing, difficulty breathing, fatigue, and weight loss. If left untreated, heartworm infection can lead to heart failure and death.

The American Heartworm Society estimates that over 1 million dogs in the United States are infected with heartworms. This number is likely much higher, as many dogs with heartworm infection do not show any symptoms.

Heartworm infection is spread through the bite of an infected mosquito. When a mosquito bites an infected dog, it ingests microfilariae, which are the immature form of heartworms. The microfilariae develop into larvae inside the mosquito and are then transmitted to another dog when the mosquito bites it.

The best way to prevent heartworm infection is to give your dog a monthly heartworm preventive. Heartworm preventives are available in a variety of forms, including tablets, chewables, and topical solutions. Your veterinarian can recommend the best heartworm preventive for your dog based on their age, weight, and lifestyle.

If your dog is diagnosed with heartworm infection, your veterinarian will recommend a treatment plan. Treatment for heartworm infection typically involves a series of injections of adulticides, which are drugs that kill adult heartworms. Your dog will also need to take antibiotics to kill any remaining microfilariae.

Treatment for heartworm infection can be long and expensive, but it is important to treat the infection as soon as possible to prevent serious complications.
