Dog Dewormer Buying Guide

Parasites will worm their way into your dog at any point in time. If you suspect that your canine has worms, then you’ll need to administer the treatment as soon as possible. After all, your dog can easily pass on his worms to other pets and family members. While a visit to your vet is important, there are plenty of over-the-counter medications that you can use if you don’t have the time, money, or capability to bring your dog to his doctor. The question is, which dewormer will work best for your dog? This in-depth guide on dog dewormers should help you understand how to find the dewormer that would eliminate the worms currently residing in your canine.

Does my dog need a dewormer?

Before you start looking for a dewormer, you need to check to see if your dog is exhibiting symptoms.

Visible worms and/or eggs

The most obvious symptom of worms is when you see worms or eggs in your dog’s feces, vomit, or fur. Worms may appear as little grains of rice or seeds because they’ve died and then dried out. Live ones may appear as small movements in his fur or feces.

Incessant scratching

If your dog never seems to stop scratching or rubbing his rear on the floor or your furniture, chances are he may have worms.

Bloated tummy

Bloated stomachs may be an indication of worms in your puppy. Your puppy can be born with worms if his mother has worms.

Change in appetite

Intestinal worms eat the same food that your dog does so your dog may end up eating more than his normal amount to make up for the food eaten by parasites. On the other end of the spectrum, some infected dogs lose their appetite.

Weight Loss

Tapeworms feed off your dog’s nutrition which can lead him to feel weak. Even if he eats his normal amount of food, if your dog is showing rapid weight loss, it may be that he has a tapeworm or whipworm using up the nutrition in his body and food.

Other symptoms include:

  • Vomiting
  • Bloody stool or diarrhea
  • Dull Coat
  • Signs of skin irritation

What types of worms are there?

There are four common types of worms found in dogs. It is important that you find out which one is in your dog so that you can administer the correct medication.


These worms hook to your dog’s intestinal walls and can cause bloody stool. Because these are often too small to be visible, you’ll need to get a sample of the stool to your vet so he can examine it under a microscope.


These worms which look like noodles can live in your dog’s intestines for a long time, growing up to six inches long. Roundworms can cause stomach bloating.


These worms live in your dog’s large intestine. They are thin, thread-like worms that are very hard to detect in feces. They can cause blood-tinged stools, diarrhea, and weight loss.


These parasites can be found in the tissue and intestines of your dog. The most common cause for this type of infection is when your dog ingests an infected flea or infected wild prey such as rodents and rabbits.

How do I find the right dewormer?

You’ll first need to confirm the worm. As we’ve mentioned, dewormers treat a variety of parasites. Some are broad-spectrum because they can treat a wide range of worms while others are very worm-specific – treating only one or two types of parasites.

There are several types of ingredients used in a dog dewormer. Pyrantel pamoate is commonly used to eliminate hookworms and roundworms. This ingredient is not effective in treating tapeworms, whipworms, or other types of intestinal parasites. The Generic Pyrantel Pamoate is a non-branded medication that contains this as its active ingredient.

Praziquantel is another medication used in dog dewormers. This one is specifically used to target tapeworms in pets. The Sentry HC WormX Plus Dog Dewormer, for example, contains pyrantel pamoate and praziquantel. Febantel and oxantel are other ingredients found in dewormers. These are used to treat whipworms. Fenbendazole is a broad-spectrum medication that can be used against giardia, roundworms, tapeworms, hookworms, and whipworms. Our number one pick, 8in1 Safeguard 4 Canine Dewormer, uses fenbendazole as its active ingredient.

Aside from checking what type of intestinal parasites are targeted by the dewormer, you also need to consider your dog’s age and size. Some dewormers like Panacur C Canine Dewormer are safe for puppies as old as six weeks as well as pregnant dogs. Some dewormers are designed specifically for large dogs such as Bayer Animal Health Quad Dewormer. If you have a puppy, the Pfizer Nemex-2 Liquid Dewormer is one of the few that are safe for puppies as young as 2 weeks old.

Any other factors I should consider?

Dewormers not only differ based on the type of intestinal parasites they treat, but they also differ in how they are administered. Some dewormers like the Panacur C Canine Dewormer are in powder form and require you to administer the medicine for 3 consecutive days. Others are in chewable tablet form like the Durvet 12-Pack Triple Wormer Tablets and only needs to be administered once.

However, the number of tablets you feed your dog may differ, depending on his weight. There are also liquid dewormers like the PetArmor Sure Shot 2X Liquid De-wormer which are also fast-acting and only require one dose. Take note that you’ll more than likely need to give your dog another dose of medication a few weeks after the first one to make sure that any worm eggs that hatched and matured are also eliminated.
