HEARTWORM DISEASE 101
Easily contracted. Potentially deadly.

70 days after a single bite from an infective mosquito, adult heartworms can reach your dog’s lungs. And then the real trouble starts: Serious and potentially fatal, heartworm disease can cause lasting damage to the blood vessels of the heart and lungs. If your dog has heartworms, you might notice signs, including coughing, difficulty breathing, sluggishness, reduced ability to exercise, and even loss of consciousness. Or you might not notice anything, as not all dogs exhibit symptoms—which is why prevention is recommended over expensive treatment that can be a prolonged, painful, and not always successful ordeal for your dog.

Intestinal Parasites 101
Hookworms & Roundworms

Just like heartworms, hookworms and roundworms are dangerous—and potentially invisible—threats to your pooch. Both can live in a dog’s intestines and cause a range of clinical signs. Roundworms are particularly troublesome, with an estimated 90+% of puppies under 3 months old infected.³

 

Unlike with heartworms, your dog can pass both hook- and roundworms to you. In fact, the CDC estimates that over 10,000 Americans get roundworms every year.⁴ Both can be contracted from either contact with contaminated soil or accidental ingestion.

Hookworms

Transmitted when

Contaminated soil is ingested • Larvae in the soil actively penetrates the skin • An infected mother nurses her puppies

Roundworms

Transmitted when

Contact is made with the feces of an infected animal • An infected mother nurses her puppies • Passed from a mother to a fetus through the placenta

Test your heartworm knowledge

Keeping your dog indoors for most of the year protects them against heartworm disease.

If your dog has heartworm disease, there will be visible signs to alert you.

False. Heartworm disease can be hard to detect. While some dogs will present persistent cough, fatigue, and fainting, others will show no signs at all.

False. Heartworms have been reported in all 50 states.

Vets need to test a dog’s blood for the presence of adult heartworms before they can prescribe HEARTGARD Plus.

True. Before a vet prescribes HEARTGARD Plus, they must determine if there is a pre-existing heartworm infection.

You should only give your dog HEARTGARD Plus during the warmer months of the year when mosquitoes are prevalent.

False. Vets recommend giving your dog a monthly preventive year-round to help protect against potentially deadly heartworm disease.

Your dog doesn’t need a monthly heartworm preventive because treatment for heartworm disease is easy and inexpensive.

False. Treatment for heartworm disease often involves complicated procedures and excessive costs. Monthly prevention is recommended instead. HEARTGARD Plus is easy-to-give—and made from real beef that dogs love.¹
