Dog Heartworm Discussion at Low Cost Pet Vet
What is heartworm disease in dogs?
Heartworm disease is a serious parasitic condition transmitted by mosquitoes. When an infected mosquito bites your dog, it can inject immature heartworm larvae into the bloodstream. These larvae travel through the body and mature into adult worms that live in the large blood vessels of the heart and lungs.
How do dogs get heartworm disease?
Dogs become infected with heartworm when they are bitten by a mosquito carrying heartworm larvae. These larvae enter the bloodstream and develop into adult worms over time. Even indoor dogs are at risk because mosquitoes can get inside homes, meaning any dog, whether indoors or outdoors, can be exposed to heartworm disease.
What are the symptoms of heartworm disease in dogs?
In many cases, dogs with heartworm disease show no symptoms at all, especially in the early stages. The most common signs, as the disease progresses, include coughing, lethargy, and exercise intolerance. Dogs may tire easily after playing or going for walks. In advanced cases, symptoms of heart failure can appear, and the dog may become very ill.
Can heartworm disease be fatal if left untreated?
Yes, if heartworm disease is not treated, it can lead to severe damage to the heart and lungs, heart failure, and even death. Early detection and treatment are critical to prevent irreversible harm to your dog’s health.
Are indoor dogs at risk for heartworm disease?
Yes, even indoor dogs can be at risk because mosquitoes can enter homes. While dogs that spend more time outdoors, especially in mosquito-heavy areas, are at higher risk, no dog is completely safe without proper heartworm prevention.
Why is early diagnosis of heartworm disease important?
The earlier heartworm disease is diagnosed, the sooner treatment can begin, helping to prevent permanent damage to your dog’s heart and lungs. Routine heartworm testing is essential, even if your dog appears perfectly healthy, as many dogs show no signs in the early stages of infection.
Heartworm Prevention in Dogs
Can heartworm disease be prevented in dogs?
Yes, heartworm disease in dogs is highly preventable with effective heartworm prevention products. There are several safe and reliable options to keep your dog protected year-round.
What are the types of heartworm prevention for dogs?
There are two main types of heartworm preventatives for dogs:
- Oral preventatives: These are typically given once a month and often protect against intestinal parasites like roundworms and hookworms in addition to heartworms.
- Injectable preventatives: These are administered by a veterinarian and can last for six months to a year, providing continuous protection against heartworm disease.
Is annual heartworm testing necessary for dogs on preventatives?
Yes, annual heartworm testing is recommended even for dogs on heartworm preventatives. This is not because the medications are ineffective, but because rare situations—like missed doses, vomiting, or spitting out medication—can leave dogs unprotected. Annual testing ensures your dog stays safe and any infection is caught early.
What should I do if my dog misses a heartworm dose?
If your dog misses a heartworm prevention dose, contact your veterinarian right away. In most cases, your vet will recommend restarting the medication and scheduling a heartworm test in six months to ensure your dog hasn’t been exposed.
Can heartworm preventatives cause side effects in dogs?
Heartworm preventatives are generally very well tolerated. Occasionally, some dogs may experience mild side effects like nausea, vomiting, or loose stool. If this happens, your veterinarian can recommend a different heartworm prevention option that works better for your dog.

How is heartworm disease diagnosed in dogs?
Heartworm disease is diagnosed through a simple blood test performed by your veterinarian. Just a few drops of blood are needed, and results are typically available within about ten minutes. If the test is positive, your veterinarian may send an additional blood sample to an external lab for confirmation. Annual heartworm testing is recommended to catch infections early and ensure your dog remains protected.
Is heartworm treatment available for dogs?
Yes, there are effective and safe treatment options for dogs with heartworm disease. Many dogs respond very well to treatment, especially when the condition is caught early. The treatment plan will depend on the severity of the disease and your dog’s overall health.
Are there risks associated with heartworm treatment?
While heartworm treatment is generally safe, there are some risks, especially in dogs with advanced heartworm disease, older dogs, or those with other medical conditions. One of the most important parts of treatment is strict rest. After treatment begins, dogs must be kept calm and confined to prevent complications. Physical activity can cause dying worms to move into the lungs, leading to a serious condition called a thromboembolic event, which can cause breathing problems and require emergency care.
How common are serious complications from heartworm treatment?
Serious complications from heartworm treatment are rare. Most dogs go through treatment without major issues, especially when they are closely monitored, and exercise restrictions are followed. Severe complications, like thromboembolic events, are uncommon but can occur if a dog becomes overly active during recovery.
