The Best Dog Dewormers

Worms. If the thought of your dog having worms gives you the heebie-jeebies, you’re not alone. Thankfully, there are numerous ways to prevent your dog from getting worms in the first place. But if you have already found worms in your pup’s stool, or have had it verified through a fecal test by your veterinarian, treating for worms is fairly simple.

Who Should Buy a Dog Dewormer

Dog dewormers should not be used as a preventative. Only treat for parasites if you are sure your dog has them. Contact your veterinarian to perform a fecal test to determine if and which kind of parasite your dog may have. Once you know which type to treat for, then you can decide which type of dewormer you need.

Preventing worms is preferable to getting rid of worms. A key factor to preventing your dog from contracting parasites is his diet. Parasites thrive on carbohydrates and sugars. Dogs who are fed kibble are at a higher risk of being infected with worms. Dogs who are fed a homemade prey-model diet, whether cooked or raw, are less likely to get parasites, due to a healthier gut and immune system.

Important Features To Consider

Dog dewormer should effectively get rid of worms in your pup. When selecting a dog dewormer, there are a few factors to consider:

  • The ingredient list. Dewormers are either natural or contain chemicals. While most dewormers are considered safe, dewormers containing fenbendazole, pyrantel, and praziquantel can cause side effects. Side effects include vomiting, diarrhea, lethargy, loss of appetite, allergic reactions, and death. Some side effects mimic the symptoms of parasites, but contact your veterinarian if your dog experiences anything out of the ordinary. Natural dewormers contain ingredients such as pumpkin seed, black walnut, grapefruit extract, apple cider vinegar, orange peel, and ginger. These natural ingredients work, but may take longer than chemical ingredients. However, they rarely trigger side effects, unless your pup happens to be allergic to one of the ingredients.
  • How to administer the dewormer. There are a number of ways to give your dog a dewormer, and which one you choose is a matter of preference. Many dewormers are offered in the form of a chewable pill that is often flavored to keep your dog’s taste buds happy. Others come in liquid form, and are administered via a dropper, whether directly into the mouth or by adding it to your pup’s food or water. Some dewormers are available as granules, which have to be added to food or water.
  • Future prevention, and other things you can do. You don’t need to rely on dewormers to prevent or treat worms. There are other things you can do to get your pup healthy. A cooked or raw prey-model diet provides the most species-appropriate diet. Probiotics and digestive enzymes can also help build gut health. The stronger your dog’s immune system is, the better chance at preventing parasites.

Frequently Asked Questions

What is a dog dewormer and how does it work?

Dog dewormers treat parasitic infections from a host of different bugs including hookworms, roundworms, whipworms, tapeworms, giardia, and more. These medicines target the worm to paralyze or kill it, and then the body expels it out through the stool.

How often should you deworm your dogs?

Regular, annual visits with your veterinarian include the stool test, which looks for abnormalities and parasites. You only need to deworm your dogs if they test positive for or present with parasites. If you suspect your dog has worms, contact your vet to get confirmation. Dogs with worms may or may not show symptoms, which is why the stool test is important.

What are signs a dog has worms?

Signs and symptoms vary depending on the dog and the parasite. Some symptoms include vomiting, diarrhea, distended stomach, coughing, scooting, weight loss, and ravenous appetite. Different parasites act differently in the body, which triggers differing symptoms. Sometimes, segments of worms may be found in your dog’s stool or around her butt. And in some cases, there are no clinical signs your dog has worms. An annual, or biannual, veterinarian exam should test for parasites.

How long until worms are gone after deworming?

Chemical dewormers tend to work quickly, and may require one to three doses, depending on the brand. They should require only one round of treatment. Natural dewormers take a little longer to work, but should help eradicate parasites within a month. Worms go through a life cycle, and treatment needs to target the full cycle.
