Essential Guide to Heartworm Prevention for Pets in Hot Weather
Summer brings sunshine, outdoor fun, and, unfortunately, an increased risk of heartworm disease for dogs and cats. As temperatures rise, so does mosquito activity—the primary way heartworms spread. Protecting your pet with proper heartworm prevention is not just important; it’s essential, especially in warmer months.
In this guide, we’ll explain what heartworms are, why prevention matters more during the summer, and how to keep your pet safe with the proper medications.
What Is Heartworm Disease?
Heartworm disease is a life-threatening illness caused by a parasite known as Dirofilaria immitis. This parasite is transmitted when an infected mosquito bites a pet, allowing the larvae to enter the bloodstream. Over time, the worms mature and settle in the heart, lungs, and nearby blood vessels—primarily in dogs, though cats can also be affected.
Without proper treatment, these worms can grow up to 12 inches long and cause serious complications such as lung damage, heart failure, and irreversible harm to internal organs, often resulting in death.
Why Summer Increases the Risk
Summer weather provides the ideal breeding conditions for mosquitoes. In warm climates, mosquito populations explode, increasing the likelihood that an infected mosquito will bite your pet.
Pets that spend more time outdoors, even for short walks, are particularly vulnerable.
Heartworm symptoms often go unnoticed until the disease has progressed. That’s why prevention is much safer, easier, and more affordable than treatment.
Why Prevention Is Better Than Cure
Treating heartworm in dogs is costly, painful, and can take several months. Even then, damage to the heart and lungs may be permanent. For cats, there’s no approved treatment, making prevention critical.
Preventive medication is the only reliable way to protect your pet. These medications kill immature heartworm larvae before they grow into adult worms.
Best Heartworm Preventive Medications for Dogs and Cats
Here are some vet-recommended heartworm preventives that also protect against fleas, ticks, and intestinal worms:
Bravecto Plus – Offers extended protection for up to 2 months against fleas, ticks, and heartworms.
These medications are easy to administer and are available as chewable tablets or topical applications.
When Should You Start Heartworm Prevention?
Heartworm prevention should be year-round. Consult your vet before starting a heartworm preventive, especially if your pet has missed doses or has never been on treatment. A simple blood test is usually required for dogs before starting heartworm prevention.
Tips to Minimize Heartworm Risk During Summer
Keep your pet indoors during peak mosquito hours (early morning and dusk).
Choose pet-safe mosquito repellents specifically formulated for animals to help protect your furry companions from bites without risking their health.
Eliminate standing water around your home—breeding grounds for mosquitoes.
Heartworm disease is preventable, but only if you take the right steps. With summer being the peak season for mosquitoes, it’s the most critical time to protect your dog or cat.
Prevention is simple, safe, and affordable compared to the costly and risky treatment of heartworm disease.

This on-line company is such a good find. They provide quality products at a good price with delivering them efficiently. Definitely recommend purchasing from them.
Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.
As a retired veterinary technician I was extremely happy to finally see a flea and heartworm medication that actually does tapeworms too!!!!!!! This is a 1st to my knowledge....I live in a tropical climate where fleas never die so this is heaven sent.
Great price, authentic quality and reliable shipping. Shipping takes a bit longer, since it is being shipped from abroad. But still a reliable service.
After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!
This is Lexi Marie! She was wondering why mom was so excited for buying flea medicine. I explained to her that we saved $100 and that she would understand some day when she grows up.
Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them.
I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions.
After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone.
Thank you very much for this mite solution. I recommend it heartily. Harry
P.S. Do not tell the Canadian vets as they will outlaw your product.
