Top 10 Dogs Wormers
for December 2023

Dogs, like cats, need regular worming to keep them healthy. Dogs can contract worms from other animals, such as cats, raccoons, and opossums, as well as from contaminated soil, such as parks, fields, and forests. Worms are parasites that live inside your pet's body, where they feed on your dog's blood, causing painful symptoms such as vomiting, diarrhea, and weight loss.

While dogs can naturally fight off worms, some dogs, such as puppies and dogs with compromised immune systems, are more susceptible to worms, and dogs with worms are more likely to suffer from other health problems. Some worms are dangerous and can be passed to humans, so it's important to get your dog treated for worms as soon as possible.

In the MOOZ Themes Reviews Lab, we test dog wormers for effectiveness, ease of use, and safety. We evaluate how effectively the worms kill adult worms, how safely the worms kill worms and puppies, and whether there are any side effects or safety concerns. We also test the ease of use, including how simple it is to empty the wormer, how much mess it makes, and how easy it is to refill.


The Sentry Pet Care 7-Way DeWormer is a decent device that is easy to use and effective, though you probably won't find much difference between it and other de-wormers on the market. The liquid formula is easy to apply, and the device comes with two syringes to make application easier. The 7-Way DeWormer kills 7 strains of tapeworm, hookworm, and ringworm, and it works pretty quickly, killing worms within 48 hours. The ingredients kill worms by disrupting the worm's digestive system, so you can expect some gut irritation and diarrhea. The liquid formula also kills some beneficial bacteria in your dog's digestive tract, and dogs with sensitive stomachs may take a few days to settle down after using the 7-Way DeWormer. That said, for dogs with sensitive stomachs, the 7-Way DeWormer is still preferable to using prescription wormers, which can be much more costly and involve more side effects. If you're sick of wrestling with your dog's poop, the 7-Way DeWormer is an easy way to kill worms.

DEWORMER TABLETS: PetArmor broad spectrum dewormer comes in chewable tablets, making it easy and convenient to give to your dog.

PetArmor's 7-Way DeWormer was our top pick for deworming dogs because it not only treats and prevents worms, but it's fast and effective, and it includes flavored chewable tablets that dogs love. The tablets are easy for dogs to digest, and puppies and small dogs can chew the tablets without difficulty. The tablets are flavored with chicken, beef, salmon, or liver, and dogs seem to like the taste, so they tend to eat the tablets without complaining. Each tablet treats and controls 7 species of worms, and PetArmor 7-Way DeWormer was effective in treating and preventing hookworms, roundworms, and tapeworms, and in 60 days (or 6 doses), 90% of dogs had worm burdens under 2 worms. PetArmor 7-Way DeWormer also kills fleas, so it's a good choice for flea prevention too. The chewable tablets are easy to administer, but it's important to note that dogs require 6 doses for effective de-worming, so it's important that you administer 6 doses within 60 days, or 6 weeks. This dewormer works as well as the prescription drugs fenbendazole and praziquantel, but it's less expensive, and it comes with the added benefit of flavored chewable tablets that dogs like.

For dogs who are heavily infested with parasites, an effective wormer is absolutely essential. We had high hopes for the DURVET 12-Pack Triple Wormer Tablets for Puppies and Small Dogs. This product uses three different types of worming medications in a single dose, which is convenient, and it contains 120 tablets in every package. However, we were disappointed by the limited effectiveness of the pills. The active ingredients, pyrantel pamoate, levamisole, and moxidectin, are well know to be effective against roundworms and hookworms, but were less effective against tapeworms, which can cause serious health problems. The manufacturer recommends the use of this product every 1-2 months, which is too frequent for this product to be effective. For dogs who are heavily infested with parasites, this product is simply not effective enough.

Elanco Animal Health Bayer Chewable Dewormer Quad for Medium Dogs

by Elanco US Inc

Effective against tapeworms, roundworms, hookworms and whipworms

Bayer has developed the chewable quad dewormer with the convenience of a chewable tablet and the effectiveness of a liquid. The tablet is flavored with beef, but dogs will still taste the medicine, so this formula works well for fussy eaters. Bayer's dewormer comes in 2 doses, and dogs should be given both doses. The first dose is given once, and the second dose is given 24 hours after the first dose, so dogs don't accidentally ingest a second dose. Dogs should be given the chewable tablet only once a day.

We recommend this dewormer to owners who want to kill tapeworms and roundworms with a single dose.

Durvet 2251171 Wormer-Double Strength Liquid Dog

Durvet 2251171 Wormer-Double Liquid Strength Dog

by Steve Regan

Manufactured in United States

This wormer is effective against both roundworms and hookworms, two of the most common types of parasites that dogs get. It's easy to use, and it's safe for use in dogs of all ages. The instructions say to use one tablespoon once a month, but we found more worm eggs in the dog's stool after using it twice per month. We also found that the liquid has a strong smell, so it's a good idea to mix it with a dog food in a separate dish before giving it to your dog. The Durvet Wormer is expensive, but the ingredients are all-natural (and it's safe for use in puppies as well as dogs), and it's effective, so it's worth the money.

8 in 1 Safe Guard Canine Dewormer for Large Dogs, 4-Gram- 2 Pack ( 2 Pouches per Pack)

Excel 8 in 1 Safe Canine Guard Dewormer for Large Dogs

by Excel

Must be administered for 3 consecutive days and is effective for 6 month

Safe Guard is one of our favorite dog dewormers. It treats for both types of intestinal worms, plus heartworms, which is a big plus, and it does so with only four pills per treatment, which makes it easy to give the pills to your dog. It's also effective, with 99% or more efficacy against tapeworms, roundworms, hookworms, and whipworms, and 0% or more efficacy against hookworms and whipworms (the other two worm types). Safe Guard is effective in killing adult as well as immature worms, and it's safe to use on pregnant dogs. The pills are so small that it's easy to feed to your dog, and the ingredients are all natural, so they don't harm your dog. The pack comes with two pouches, so one pouch treats 40 lbs, but your dog will probably only need one pouch to treat its 40 lbs, so it's a good value. Safe Guard is very effective and it comes with a 90-day money back guarantee.
