Overview of Heartworms in Dogs

Heartworm disease is a serious and potentially deadly affliction caused by the parasitic roundworm, Dirofilaria immitis. Heartworms are spread to dogs from mosquitos that carry the larval stage of the Dirofilaria Immitis, thus leaving dogs at risk of these harmful parasites. If left untreated, heartworms can cause severe damage to a dog’s organs, as well as permanent disability, even death. Because of this, it is essential for all dog owners to be informed about the ways to both prevent and treat heartworms in dogs.

How Does Heartworm Disease Develop?

Heartworm disease begins when a dog is bitten by an infected mosquito. The small larvae of the heartworm then travel through a dog’s bloodstream and develop into adult worms. These adult worms can live up to seven years in a dog’s heart and pulmonary arteries, and if the dog is untreated, the number of worms can grow to be very high, leading to more severe damage.

Signs of Heartworm Disease

One of the most noticeable signs of heartworm disease is a persistent cough and difficulty breathing. Other signs of heartworm disease include loss of appetite, lethargy, weight loss, and reluctance to exercise.

Treatment of Heartworm Disease

Treatment of heartworm disease involves killing the adult heartworms and then treating the damage they’ve caused. The most common treatment is an injection, which kills the adult heartworms. After that, the dog is given medications to help rebuild the damage caused by the heartworms and to reduce inflammation.

Preventing Heartworm Disease

The best way to prevent heartworm disease is to use an appropriate preventative medication. These medications are usually given every month, and contain drugs that kill the immature forms of the Dirofilaria immitis if your dog is bitten by a mosquito carrying it.

Screening for Heartworm Disease

Heartworm disease can also be screened for in your dog’s blood. This step is essential for detecting the disease early, before it has had time to cause serious damage. It is important to screen for heartworm disease regularly, as it can take up to six months for the tests to detect the presence of heartworm disease in your dog.

Symptom Treatment

Your vet may also recommend additional medications to reduce symptoms associated with heartworm disease, such as pain and inflammation. These medications will not cure your dog, but can make them more comfortable while they are undergoing treatment.

Home Care

Dogs undergoing treatment for heartworm disease will need to be monitored closely at home. Your vet will likely recommend an exercise and activity plan specifically tailored to your dog’s treatment. Additionally, your vet may recommend additional supplements to help support your dog’s health during treatment.

Reinfection Prevention

After your dog has completed treatment for heartworm disease, it is important to continue to use a preventative medication to help prevent reinfection. This is especially true for dogs living in areas with a high prevalence of mosquitos.
