Heartworm in Dogs - Prevention & Treatment

Mosquitos can spread parasites known as heartworms, which can infect the heart and lungs of your furry friend. Our vets in Los Angeles discuss heartworm in dogs, the signs to watch for, and how to prevent infection.

Heartworm in Dogs

The blood-borne parasite Dirofilaria immitis is responsible for causing canine heartworm disease, which can be transmitted to dogs worldwide by over 30 different species of mosquitoes.

When an infected mosquito bites your pet, the worms can grow into adults, reproduce, and thrive in your pet's heart. Organ damage, heart failure, and severe lung disease can result from the condition.

Signs of Heartworm in Dogs

In the early stages of heartworm, dogs may show minimal or no symptoms. However, as the condition worsens, they may experience weight loss, fatigue even after moderate activity, breathing difficulties, decreased appetite, and a mild but persistent cough.

When heartworm disease reaches its advanced stages, excess fluid in the abdomen may swell your dog's belly. Heart failure can also affect pets.

How are heartworm infections diagnosed in dogs?

Your vet can detect the proteins heartworms release into the bloodstream by conducting blood tests. You can detect the earliest heartworm proteins about five months after your pet becomes infected.

We strongly advise getting your dog tested for heartworm yearly. Make sure to give your pup annual heartworm preventive treatments. Our vets highly emphasize the prevention of heartworm disease in Los Angeles. Taking proactive measures to protect your dog rather than waiting to treat the disease if they become infected is crucial.

How is heartworm in dogs treated?

Treatment for heartworm disease can have serious complications for your pet's health and may be toxic for your pooch. However, there are available options. Consulting with your vet will assist you in determining the most suitable options for your pet.

The veterinarian administers an arsenic-containing drug called melarsomine dihydrochloride by injecting it into the pet's back muscles. This treatment effectively targets and eliminates heartworms. Pets can benefit from this FDA-approved drug, as it effectively eliminates adult heartworms. You can also apply FDA-approved topical solutions to your pet's skin to eliminate parasites in their bloodstream.

Treating heartworm disease in your pet can be quite costly. It requires multiple visits to the veterinarian, bloodwork, X-rays, hospitalization, and a series of injections.

Are there heartworm prevention medications?

Heartworm prevention medications are available from your vet. Even if your dog is already on preventive heartworm medication, annual blood tests for heartworm are recommended.

Heartworm prevention is safer, easier, and more affordable than treating the disease. The prevention treatment may also protect your pet against other parasites, such as roundworms, hookworms and whipworms.

Your pup should start receiving preventive care for heartworms by no later than eight weeks of age. There is an at-home option that you can administer every month, or you can bring them to your vet every six months for a dose of professional-grade medicine.
