7 Best Dewormers for Puppies and Adults

Puppies and adult dogs often have intestinal worms at some point in their lives. Drugs used for deworming aid in the digestion and death of worms, allowing them to be flushed out of your dog’s system. Worms are a frequent problem in dogs, so your doctor may prescribe giving your dog a dewormer regularly.

Whether your dog or puppy has worms or not, we’ll tell you how to tell if they have them and what kind of dewormer to use.

Bayer Quad Dewormer (Best Quality)

These chewable tablets by Bayer kill hookworms, roundworms, tapeworms, and whipworms. Praziquantel, pyrantel pamoate, and febantel are the same active components included in the widely recommended dewormer Drontal Plus. But this substance is available without a doctor’s prescription.

Our top recommendation for puppy dewormer is Bayer Quad, which may be given to dogs as young as three weeks old without risk. However, many other brands shouldn’t be given to pups until they are at least six weeks old.

Still, it works well with canines of any age. A single dose is all that is needed. It comes in a chewable form, but it may also be crushed and sprinkled on your dog’s food. People who have used it on their pets have reported that it is successful; nevertheless, some users have had nausea and vomiting.


  • Identical components as Drontal Plus, which is given by veterinarians
  • Effective against four different kinds of worms
  • No more than one dosage is needed
  • Generally considered safe for pups when they reach the age of 3 weeks


  • It’s not good for females that are expecting puppies
  • Costs more than one may expect.
  • There have been a few complaints of nausea and vomiting.

Panacur C Canine Dewormer (Most effective)

The most common types of worms, such as hookworms, roundworms, tapeworms, and whipworms, are treated effectively. Dogs of all ages, including pregnant and nursing mothers, may take it without risk. This powdered medicine should be given to your dog once daily for three days.

Panacur C should be mixed with water before being given to a dog that eats dry dog chow. You may buy it in 1, 2, or 4-gram portions. There are three servings in each package.

Following their dosage advice, there must be approximately one gram of powder for every 10 pounds of your dog’s weight (so a 50-pound dog would receive a five-gram dose per day). You will need to select the appropriate packet size(s).


  • It is widely recommended by veterinarians.
  • Effective against four different kinds of adult worms
  • Non-hazardous for nursing or pregnant dogs


  • It must be given for three days in a row

Sentry WormX Plus (Best Price)

The manufacturer suggests this product for dogs over the age of 12 weeks; there are two pills in a container; the recommended dosage will depend on your dog’s weight.

Dogs weighing more than 100 pounds each may need many packages. The tablets’ size has been cited as a concern by certain users, who say the pills are excessively big and difficult to swallow. In addition, a few consumers have complained of weight loss, and nausea.


  • Extremely good price.
  • Removes common species of worm
  • No more than one dosage is needed.
  • No more worms in feces the next week


  • Dogs under 12 weeks old or those who are expecting or nursing puppies should not consume this product.

  • There have been some complaints of nausea and vomiting.

Sentry HC WormX Plus (Best Rating)

These chewable pills are flavored to appeal to a dog’s sense of taste and may be given as a treat or mixed into your pet’s regular diet.

Dogs weighing 6–25 pounds may use Sentry HC WormX Dewormer Tablets. Give one tablet for canines weighing 6-12 pounds; for canines weighing 12–25 pounds, give two tablets. Puppies and dogs weighing more than 6 pounds can safely take these pills.

Pregnant or breastfeeding females should avoid using these medications until their safety has been established.


  • Among the wormers we researched, Sentry HC WormX Plus Dog Wormer received the most rating.
  • It was well-received by owners for being both simple and effective in ridding their dogs of worms.
  • Unlike other medications (usually those containing fenbendazole), this one will successfully eliminate dog tapeworms (Dipylidium caninum).

You may either pour the liquid wormer into your dog’s open mouth or mix it with his food to give it to him. It is recommended to give this medicine at a dose of one teaspoon (5 milliliters) per 10 pounds of body weight.

It is suitable for both puppies and adult dogs. Females who are pregnant or who are nursing should avoid this. The manufacturer suggests giving this drug once a month. The drug comes with a measuring cup so that the right dose may be given quickly and easily.


  • Most of the owners who tested it were pleased with it.
  • According to some reviews, it successfully eliminated roundworms in canine patients.
  • This is a suitable option if your dog appears to have roundworms or hookworm larvae but not tapeworms.

Durvet Triple Dog Wormer

These pills come in packs of 12 and may be mixed with your dog’s food or given separately as a treat. One pill should be taken for every 25 to 50 pounds of body weight.

  • Amazon’s Choice Product
  • Effective for tapeworms, roundworms, and some species of hookworms

How long does it take a dewormer to work on dogs? 

Treatments to eliminate common worms have an immediate impact. For example, researchers have shown that deworming drugs have a 98%–100% success rate in getting rid of roundworms and other types of parasites often seen in newborn pups. Natural dewormers like pumpkin seeds may work slower but are recommended for sensitive tummies.

How do you know if a dog dewormer is working? 

While some worms will be eliminated via the dog’s digestive system, others may be paralyzed by the drug and expelled in the dog’s infected feces or vomit. Your dog’s general health and appearance might improve if the active ingredients of the dewormer are working and the worms are leaving the body.

Can I feed my dog after deworming? 

Keep a watch on your dog for at least two to three hours after giving them the worming pill since vomiting is a common side effect of any oral therapy. To avoid this, consider giving them food along with the medication.

What happens if you give a dog too much wormer? 

Moderate and severe side effects may occur if a dog is given too much wormer. An overdose of worm medication may include nausea, vomiting, and diarrhea. If you think your dog has eaten more than he should, you should talk to a vet immediately.

Even for heartworm preventatives, consulting your vet is a must.

How Often Should I Deworm My Dog?

If your dog ever shows signs of having worms, he must be treated immediately. However, many veterinarians and owners also give over-the-counter dewormers to their dogs on a monthly basis to prevent any type of worm infestation.

Puppies should be wormed once a month until they are six months old. Puppies need to go through this series of procedures quite quickly for three reasons:

  1. Due to their fragile immune systems, puppies are more susceptible to worm infection and have more severe symptoms than adult dogs;
  2. in addition to their mother, the puppies in a litter are often quite close to their siblings.
  3. Females commonly transmit worm larvae to their pups through breast milk.

Adults, on the other hand, maybe wormed as frequently as monthly if heartworm or lungworm prevention is used or whenever an infection is detected (once or twice yearly for intestinal parasites).

In addition, veterinarians often deworm dogs who haven’t been seen in a while, just to be safe. A deworming medication used to treat canine heartworm disease are distinct from those used to treat intestinal worms. Although most heartworm counter medication is given once a month, your doctor will explain the specific dose plan.
