The heartworm looks like a long white worm and lives in a dog’s heart. It can also live in the blood vessels near the heart and lungs.
Heartworms are easily preventable. They can be fatal if not treated. The treatment can cause serious side effects.
Mosquitoes spread heartworms.
When a mosquito bites an infected dog, it ingests immature heartworms, which mature inside the mosquito. If that same mosquito bites your dog, your dog will get infected.

If you catch heartworms early enough, there is a great chance for treatment to be successful.
Baby Heartworms: Heartworm preventives will kill baby heartworms. In most cases, your veterinarian will admit your dog to the hospital for observation, and then do another blood test to make sure the heartworms are gone.
Adult Heartworms: If your dog has adult worms, the baby worms must be treated first. Your veterinarian will recommend 1 to 3 months of a preventive treatment before treating the adult worms.
Once the baby worms are gone, your veterinarian will most likely prescribe three doses of ImmiticideTM.
After treatment, you must make sure your dog has complete rest to prevent lung damage from the decomposing worms. Avoid exercise for at least a month, and gradually return to normal activity.
Extremely serious heartworm cases may require surgical removal of the worms.
If your dog had heartworms and was treated, it can get the disease again if you are not careful to follow a monthly preventive plan.
