Protect your dog against the scourge of heartworms with preventative heartworm medicine. Chewy carries many types of heartworm medication for dogs, including heartworm pills, topical heartworm medications, and combination products that kill other parasites too.
Your vet is the person to ask about the best heartworm prevention for dogs. Your vet should be up to date on all the latest products available and can advise you on which ones may be best for your pup. For owners of younger dogs, it is important to ask about heartworm medicine for puppies, as younger pups need protection as well. Heartworm medication is available only by prescription, and your vet will need to perform a heartworm test before prescribing any preventatives. If your dog tests positive for heartworms, he will need to undergo heartworm treatment to eliminate the dangerous parasites.
Once your dog has tested negative for heartworms or completed heartworm treatment, he can begin the heartworm preventative regimen recommended and prescribed by his vet. You should have the option of choosing between oral heartworm medications in pill, chewable tablet or soft chew form or a heartworm preventative medicine applied as a topical. Most heartworm medicines provide protection for up to a month, and some are available as combo treatments that protect against roundworms, hookworms, tapeworms and more.
You can also choose combination products that combine heartworm medicine with prescription flea & tick medication in one easy dose for convenience. There are many options for heartworm protection and choosing the right one is important. The Chewy pet pharmacy has many medications needed to keep your pets healthy and safe, including prescription dog medicine for a variety of ailments, flea & tick medication for cats and medications for your other pets too. Shop our wide selection of heartworm medicine so you can protect your best friend 24/7.

Why is dog heartworm medicine only available with a prescription?
Dog heartworm medicine is only available with a prescription because your dog needs a heartworm test to ensure he isn’t already infected first. Giving a heartworm preventative to a dog who is already infected can be dangerous or even deadly. A vet can also determine the right dosage for your pet and suggest the right products for your dog’s lifestyle, health and age.
Do dogs need heartworm medicine in the winter?
Dogs need heartworm medicine in the winter, spring, fall and summer because the danger of failing to protect them is too great. Although there are fewer mosquitos around during winter in most climates, there is still the risk of a bite and heartworm contraction. Protect your best friend year-round from heartworms for safety and peace of mind.
