Is Heartworm Prevention Necessary For My Pet?

Heartworms are parasitic roundworms spread by mosquito bites. When the larvae enter an animal's body, they grow into adult worms that settle in the lungs and heart, leading to severe damage. Heartworm disease can cause breathing issues, blood clots, and heart problems, and it can be deadly if not treated.

Is Your Pet At Risk Due To Heartworm?

It's important to note that heartworms and heartworm disease are not transmitted through direct contact. They are exclusively spread by mosquitoes. This means that any dog or cat living in an area with mosquitoes is potentially at risk.

Mosquitoes can be active year-round in many regions, not just during the summer. They can also live indoors during winter, so keeping pets inside doesn't ensure they are safe from heartworm infection.

Although many believe cats are less susceptible to heartworm than dogs, they are still at risk. While heartworms are less likely to mature in cats, the consequences can be just as severe if they do.

Why Is Heartworm Prevention Important?

Heartworm disease in dogs  can be treated, but the treatment is lengthy, potentially risky, and expensive. Moreover, even after treatment, heartworms can still cause permanent organ damage. Fortunately, heartworms can be completely prevented with medication.

Prevention is especially crucial for cats since there is no treatment for adult heartworms in felines. The medication used for dogs is unsafe for cats, so the focus is on managing symptoms and maintaining the cat's health until the heartworms die, which can take 2-3 years.

How Heartworm Treatment Works?

Heartworm medication for your dog or cat is preventive; it does not treat existing heartworm disease. Before starting any heartworm medication, it's essential to test and, if necessary, treat your pet for adult heartworms. Administering a preventive to a heartworm-positive pet can be dangerous.

This medication doesn't prevent mosquito bites but eliminates heartworm larvae before they mature. Therefore, it's crucial to consistently give your pet their monthly heartworm preventive. Regular treatment ensures larvae are killed before they can become adult worms.

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.

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.

Customer photo review of Revolution Plus For Medium Cats 5.6-11 lbs (2.6-5kg)

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.
