Not much to add. Dog tolerates it and price is good

Two names often stand out when it comes to protecting your dog from harmful parasites like heartworms, fleas, and intestinal worms: Heartgard Plus and Revolution. Veterinarians and pet owners trust them, but they serve slightly different purposes. Selecting the best product for your dog relies on factors like your dog’s daily routine, specific health requirements, and the climate in your area.
This article explores Heartgard Plus and Revolution by examining their modes of action, the parasites they target, how they are administered, and their main advantages and disadvantages — all to help you determine the best choice for your dog.

Heartgard Plus is a monthly chewable that protects dogs from heartworm disease and treats and controls roundworms and hookworms. It contains ivermectin and pyrantel — two active ingredients that kill parasites before they cause serious health issues.

Revolution is a topical (spot-on) treatment that offers broad-spectrum protection. It prevents heartworms, fleas, ear mites, sarcoptic mange, and even ticks in some versions, like Revolution Plus (for cats) or Revolution for dogs.
It contains selamectin, which is absorbed through the skin into the bloodstream and affects a wide range of internal and external parasites.

Let’s break down the core differences to make your decision easier.
The answer depends on your dog’s needs and where you live. Let’s look at a few scenarios:
Some pet parents even use Heartgard Plus for heartworm and intestinal worms, and another flea/tick topical for full coverage. However, it's important to check with your veterinarian before using multiple products together.
Both Heartgard Plus and Revolution are FDA-approved and considered safe for most dogs. However, mild side effects can occur:
Always follow dosage instructions and discuss any reactions with your veterinarian.
Cost is another factor to consider:
Buying in larger packs (6 or 12 months) online often saves money. Both medications can be found at discounted rates from trusted pet pharmacies.
There is no one-size-fits-all answer, but here's a quick summary:
Whichever you choose, consistent monthly prevention is key to keeping your dog safe and healthy. Consult your veterinarian to get tailored guidance based on your dog’s lifestyle and potential risk factors.
