Heartgard, when administered correctly and consistently, is generally highly effective. Its failure rate is primarily associated with either owner non-compliance (missed or late doses) or, in specific geographic regions, parasite resistance.

Prognosis: heartworm treatment success rates
With the three-dose adulticide protocol described above, in conjunction with doxycycline and macrocyclic lactones as recommended by the American Heartworm Society, 98% of dogs will be cleared of heartworm infection.

With more than 30 years of proven protection, the heartworm disease preventive in HEARTGARD Plus chews has been trusted over 2 billion times.
However, Heartgard Plus Chewables cannot prevent the development of the adult stage. Use with caution for collies and other herding dog breeds. These breeds have been known to have adverse reactions to ivermectin at elevated dose levels.
It is most commonly seen in herding breeds, such as Collies, Old English Sheepdogs, and Australian Shepherds, but can be found in any breed. The normal MDR1 gene in dogs produces a protein (P-glycoprotein) that helps to excrete and eliminate drugs.
The Importance of Year-Round Prevention
In Georgia, mosquitoes are active for much of the year, which means your dog could be exposed to heartworm-carrying mosquitoes at any time. Year-round heartworm prevention is the best way to ensure your dog is protected from this life-threatening disease.
5 Signs Your Dog May Have Heartworm Disease
All dogs need parasite prevention to protect against heartworms and intestinal worms. Ivermectin (Heartgard, Stromectol) has long been considered a safe and effective parasite preventative for dogs.
Hunting breeds or breeds frequently run at field trials may often appear to be more susceptible to heartworm infection. Because these dogs spend a great deal of time in the field, they are probably fed upon by mosquitoes to a greater extent than are some other breeds.
Heartworm is a progressive, life-threatening disease. The earlier it is detected and treated, the better the chances that your pet will recover and have less complications. Dogs: As with most medical problems, it is much better to prevent heartworm infection than to treat it.
Many dogs treated for heartworm have close to a normal life expectancy, depending on how quickly the disease was found. Without treatment, heartworm disease will shorten a dog's natural life expectancy.
If you have a breeding dog, a pregnant dog, or a puppy between 6 and 8 weeks old, Heartgard Plus is the safest option. If you're hoping to find a broad-spectrum product that protects against fleas and ticks while it defends against internal parasites, Simparica Trio is the clear winner.
The leading cause of death in dogs, especially older dogs, is cancer (neoplasia), affecting about 1 in 4 dogs, similar to humans, with specific breeds at higher risk. Other significant causes include old age, heart disease, digestive disorders (like bloat), infectious diseases (like Parvo), and trauma, with sterilization influencing risks for cancer and infections.
There is now ample evidence that at least one strain of heartworms has developed resistance to some of the market's best-known preventives. In addition, there is evidence to suggest that one of the most popular heartworm preventives, Heartgard, has an efficacy rate of less than 100 percent.
Also bring a fresh stool sample for them to check for the presence of worms. Finding microscopic intestinal worm eggs in the stool is the most common way to diagnose worms in dogs. Heartworms are diagnosed with a blood test, an X-ray of the chest, or an ultrasound of the heart.
Microfilariae must pass through a mosquito to become infective larvae. When the infected mosquito bites another dog, the mosquito spreads the infective larvae to the dog through the bite wound. In the newly infected dog, it takes about 6 to 7 months for the infective larvae to mature into adult heartworms.
The cough associated with heartworm disease in dogs is often likened to the sound of a goose honking. If your dog tends to get into coughing fits after activity or eating, and if those coughs sound harsh and honk-like, then she may have heartworm disease or another heart related concern.
Heartworm preventatives work by targeting immature heartworm larvae soon after infection, stopping their development before they can settle in your pet's heart and lungs. Skipping a dose leaves an opening, however short, for those larvae to slip through and start growing undetected.
It is transmitted through the bite of an infected mosquito. Mosquitoes carry the immature stages of the heartworm as a result of previously feeding on an infected dog, coyote, wolf, or fox. After biting an unprotected dog, the heartworm larvae work their way to the heart and pulmonary artery, where the damage begins.
Approximately 1 in 500 cats nationwide test positive for heartworms each year. Heartworm rates are higher in Texas, Mississippi, Alabama and Louisiana, where 1 in 200 cats tested positive (see Louisiana-specific news release).
Give your dog a HEARTGARD Plus chew once a month, year-round. How long does a dose of HEARTGARD Plus chews last? Even though the dose of a HEARTGARD Plus chew only remains in the dog for a few days, each HEARTGARD Plus chew works by affecting parasitic infections acquired during the previous month/30 days.
Anecdotal evidence suggests that herbs such as garlic, black walnut and wormwood, and the homeopathic heartworm nosode, may actually prevent as well as treat infection. Unfortunately, I have not yet been able to find substantive proof that these therapies can reliably and safely prevent or treat infection or disease.
