When should I start my puppy on heartworm prevention?

According to the American Heartworm Society the risk of puppies getting heartworm disease is equal to that of adult pets. The American Heartworm Society recommends that puppies be started on a heartworm preventative as early as the product label allows, and no later than 8 weeks of age.


When should I test my dog for heartworm?

It takes approximately 6 months for heartworm disease to show up in the blood test. So, the American Heartworm Society Recommends testing your dog at 7 months, and then annually. Even when your pet is on heartworm prevention, there is the chance of breakthrough, so a yearly test ensures that if your pet were to become positive, it would be caught early on and cause less damage to your pet’s health. 



How many months a year should I give Heartworm Prevention?


 Dogs just don’t need prevention in the warm months. Heartworm preventives work by treating heartworms that already infected the pet within the past month or longer; meanwhile, preventives need to be given on time, every time to be effective. The American Heartworm Society recommends your pet be kept on heartworm prevention 12 months a year. 


Even if your pet doesn’t go outside, it is at risk for heartworm disease. Heartworm disease is transmitted through mosquitos, and mosquitos can go inside too.

Does Heartworm Prevention do more than just help prevent heartworm?


Almost all of our heartworm preventives that we carry not only protect your pet from heartworm, but they are effective against certain intestinal parasites. Depending on the product, these may include hookworms, roundworms, whipworms, and tapeworms. 

Consult with your veterinary clinic to determine the best product for your pet.

Why Is It Important?


Contrary to what many pet owners believe, protecting dogs and cats from parasites requires a year-round commitment. Although fleas, and ticks are known to thrive in warmer climates, they don’t disappear when the temperature drops. 




Fleas are the most common type of external parasite found on cats and dogs; fleas are more than just a seasonal annoyance. Even though fleas thrive primarily in humid environments above 70 degrees, they can survive near freezing temperatures and are not entirely inactive during winter.


Once the fleas are on your pet, they can multiply quickly. Remember that the adult fleas you see on your pet only account for a small percentage of the potential population in your home. More than 90% are still in the immature stages (eggs, larvae, and pupae) and pose a looming threat.


  • Did you know that fleas don’t fly, but the average flea can jump as far as 12 inches forward and 7 inches high.

  • One flea can bite your pet up to 400 times a day.


Keeping your pet on prevention throughout the year is the best way to protect your pet.




Turns out, these tiny ticks are very resourceful. Rather than dying off in the winter they seek shelter among fallen leaves in wooded areas they normally inhabit. At the first sign of milder weather they emerge in search of a meal. Some disease-carrying species of ticks may stay active as long as the climate remains above freezing and isn’t to icy or wet.


Ticks latch on to pets and people by burrowing into the skin, producing a glue-like substance to stay attached and feeding on their hosts blood for days. Without regular prevention, it can be hard to stop a tick from attaching to an animal. It’s important to know that your pet can encounter ticks outside the woods too. They can be found in trees, woodpiles, and under leaves. Since pets are low to the ground, ticks can attach to their fur quickly and crawl down to the skin, where they will attach.


In addition to Lyme disease, a variety of other tick-transmitted diseases ad infections could harm your pet. Regardless of whether you think your pet is likely to come in contact with these harmful pests, its crucial to provide year long protection.


  • Ticks are not insects they’re arachnids, related to spiders and scorpions.

  • Ticks crawl, they don’t jump, fly or drop from trees. That’s why pets are susceptible.

  • Some ticks inject a substance that acts like a local anesthetic, so your pet unwittingly provides a tick with dinner and a ride.

All of the information below is from the American Heartworm Society.

Heartworm disease is a serious and potentially fatal disease in pets in the United States and many other parts of the world. It is caused by foot-long worms (heartworms) that live in the heart, lungs and associated blood vessels of affected pets, causing severe lung disease, heart failure and damage to other organs in the body. Heartworm disease affects dogs, cats and ferrets, but heartworms also live in other mammal species, including wolves, coyotes, foxes, sea lions and—in rare instances—humans. Because wild species such as foxes and coyotes live in proximity to many urban areas, they are considered important carriers of the disease.



The dog is a natural host for heartworms, which means that heartworms that live inside the dog mature into adults, mate and produce offspring. If untreated, their numbers can increase, and dogs have been known to harbor several hundred worms in their bodies. Heartworm disease causes lasting damage to the heart, lungs and arteries, and can affect the dog’s health and quality of life long after the parasites are gone. For this reason, heartworm prevention for dogs is by far the best option, and treatment—when needed—should be administered as early in the course of the disease as possible. Learn more about heartworm medicine for dogs.



Heartworm disease in cats is very different from heartworm disease in dogs. The cat is an atypical host for heartworms, and most worms in cats do not survive to the adult stage. Cats with adult heartworms typically have just one to three worms, and many cats affected by heartworms have no adult worms. While this means heartworm disease often goes undiagnosed in cats, it’s important to understand that even immature worms cause real damage in the form of a condition known as heartworm associated respiratory disease (HARD). Moreover, the medication used to treat heartworm infections in dogs cannot be used in cats, so prevention is the only means of protecting cats from the effects of heartworm disease.

How is heartworm disease transmitted from one pet to another?
The mosquito plays an essential role in the heartworm life cycle. Adult female heartworms living in an infected dog, fox, coyote, or wolf produce microscopic baby worms called microfilaria that circulate in the bloodstream. When a mosquito bites and takes a blood meal from an infected animal, it picks up these baby worms, which develop and mature into “infective stage” larvae over a period of 10 to 14 days. Then, when the infected mosquito bites another dog, cat, or susceptible wild animal, the infective larvae are deposited onto the surface of the animal's skin and enter the new host through the mosquito’s bite wound. Once inside a new host, it takes approximately 6 months for the larvae to develop into sexually mature adult heartworms. Once mature, heartworms can live for 5 to 7 years in dogs and up to 2 or 3 years in cats. Because of the longevity of these worms, each mosquito season can lead to an increasing number of worms in an infected pet.
What are the signs of
heartworm disease in DOGS?

In the early stages of the disease, many dogs show few symptoms or no symptoms at all. The longer the infection persists, the more likely symptoms will develop. Active dogs, dogs heavily infected with heartworms, or those with other health problems often show pronounced clinical signs.

Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. As heartworm disease progresses, pets may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen. Dogs with large numbers of heartworms can develop a sudden blockages of blood flow within the heart leading to a life-threatening form of cardiovascular collapse. This is called caval syndrome, and is marked by a sudden onset of labored breathing, pale gums, and dark bloody or coffee-colored urine. Without prompt surgical removal of the heartworm blockage, few dogs survive.

What are the signs of
heartworm disease in CATS?

Signs of heartworm disease in cats can be very subtle or very dramatic. Symptoms may include coughing, asthma-like attacks, periodic vomiting, lack of appetite, or weight loss. Occasionally an affected cat may have difficulty walking, experience fainting or seizures, or suffer from fluid accumulation in the abdomen. Unfortunately, the first sign in some cases is sudden collapse of the cat, or sudden death.

How significant is my pet's risk for heartworm infection?

Many factors must be considered, even if heartworms do not seem to be a problem in your local area. Your community may have a greater incidence of heartworm disease than you realize—or you may unknowingly travel with your pet to an area where heartworms are more common. Heartworm disease is also spreading to new regions of the country each year. Stray and neglected dogs and certain wildlife such as coyotes, wolves, and foxes can be carriers of heartworms. Mosquitoes blown great distances by the wind and the relocation of infected pets to previously uninfected areas also contribute to the spread of heartworm disease (this happened following Hurricane Katrina when 250,000 pets, many of them infected with heartworms, were “adopted” and shipped throughout the country).

The fact is that heartworm disease has been diagnosed in all 50 states, and risk factors are impossible to predict. Multiple variables, from climate variations to the presence of wildlife carriers, cause rates of infections to vary dramatically from year to year—even within communities. And because infected mosquitoes can come inside, both outdoor and indoor pets are at risk.

The American Heartworm Society Recommends

“THINK 12”

1. Get your pet tested every 12 months for heartworm


2. Give your pet heartworm preventive 12 months a year

What do I need to know about heartworm testing?

Heartworm disease is a serious, progressive disease. The earlier it is detected, the better the chances the pet will recover. There are few, if any, early signs of disease when a dog or cat is infected with heartworms, so detecting their presence with a heartworm test administered by a veterinarian is important. The test requires just a small blood sample from your pet, and it works by detecting the presence of heartworm proteins. Some veterinarians process heartworm tests right in their hospitals while others send the samples to a diagnostic laboratory. In either case, results are obtained quickly. If your pet tests positive, further tests may be ordered.

When should my pet be tested?

Testing procedures and timing differ somewhat between dogs and cats.

Dogs. All dogs should be tested annually for heartworm infection, and this can usually be done during a routine visit for preventive care. Following are guidelines on testing and timing:

  • Puppies under 7 months of age can be started on heartworm prevention without a heartworm test (it takes at least 6 months for a dog to test positive after it has been infected), but should be tested 6 months after your initial visit, tested again 6 months later and yearly after that to ensure they are heartworm-free.

  • Adult dogs over 7 months of age and previously not on a preventive need to be tested prior to starting heartworm prevention.  They, too, need to be tested 6 months and 12 months later and annually after that.

  • You need to consult your veterinarian, and immediately re-start your dog on monthly preventive—then retest your dog 6 months later. The reason for re-testing is that heartworms must be approximately 7 months old before the infection can be diagnosed.

Annual testing is necessary, even when dogs are on heartworm prevention year-round, to ensure that the prevention program is working. Heartworm medications are highly effective, but dogs can still become infected. If you miss just one dose of a monthly medication—or give it late—it can leave your dog unprotected. Even if you give the medication as recommended, your dog may spit out or vomit a heartworm pill—or rub off a topical medication. Heartworm preventives are highly effective, but not 100 percent effective. If you don’t get your dog test, you won’t know your dog needs treatment.

What happens if my dog tests positive
for heartworms?

No one wants to hear that their dog has heartworm, but the good news is that most infected dogs can be successfully treated. The goal is to first stabilize your dog if he is showing signs of disease, then kill all adult and immature worms while keeping the side effects of treatment to a minimum.

Here's what you should expect if your dog tests positive:

Confirm the diagnosis. Once a dog tests positive on an antigen test, the diagnosis should be confirmed with an additional—and different—test. Because the treatment regimen for heartworm is both expensive and complex, your veterinarian will want to be absolutely sure that treatment is necessary.

Restrict exercise. This requirement might be difficult to adhere to, especially if your dog is accustomed to being active. But your dog’s normal physical activities must be restricted as soon as the diagnosis is confirmed, because physical exertion increases the rate at which the heartworms cause damage in the heart and lungs. The more severe the symptoms, the less activity your dog should have.

Stabilize your dog's disease. Before actual heartworm treatment can begin, your dog’s condition may need to be stabilized with appropriate therapy. In severe cases of heartworm disease, or when a dog has another serious condition, the process can take several months.

Administer treatment. Once your veterinarian has determined your dog is stable and ready for heartworm treatment, he or she will recommend a treatment protocol involving several steps. The American Heartworm Society has guidelines for developing this plan of attack. Dogs with no signs or mild signs of heartworm disease, such as cough or exercise intolerance, have a high success rate with treatment. More severe disease can also be successfully treated, but the possibility of complications is greater. The severity of heartworm disease does not always correlate with the severity of symptoms, and dogs with many worms may have few or no symptoms early in the course of the disease.

Test (and prevent) for success. Approximately 6 months after treatment is completed, your veterinarian will perform a heartworm test to confirm that all heartworms have been eliminated. To avoid the possibility of your dog contracting heartworm disease again, you will want to administer heartworm prevention year-round for the rest of his life.
