6. Durvet Triple Wormer

The Durvet Triple Wormer comes in two packages – 12 or 2 tablets. This could be purchased without any prescription.

Unlike a lot of dewormers available on the market wherein the treatment lasts for three days; this one from Durvet only requires one dose for just one day.

These tablets are seafood-flavored and chewable. Each contains 114 mg of Pyrantel Pamoate and 114 mg of Praziquantel which are both effective on different strains of tape, hook, and roundworms.

If you are curious about the types of worms this product could treat, here is a guide you can check:

  • Tapeworms: Dipylidium Caninum (most common) and Taenia Pisiformis
  • Roundworms: Toxocara Canis and Toxascaris Leonina
  • Hookworms: Ancylostoma Caninum, Ancylostoma Braziliens, and Uncinaria Stenocephala

Some dog owners are also using these tablets as a preventive supplement as they find the product safe and effective in preventing worms.

Now, if you are a breeder or you’re trying to deworm your pregnant dog, then you may want to choose something else because as of now, this product is not yet proven safe for breeding and pregnant dogs.

For pet owners who already purchased this product, they didn’t like that it doesn’t treat heartworms and that the instructions don’t include the dosing schedule. For possible side effects, some owners reported that their dogs had diarrhea during treatment.



5. Bayer Animal Health

The Bayer Animal Health dewormer comes as beef-flavored chewable tablets. This is for dogs and puppies that are three weeks and up, and as long as they weigh more than two pounds.

This brand has different packages that are specific to small, medium, and large dogs that weigh 45 lbs. and up.

The box for puppies and small dogs (2 – 25 lbs.) contains four tablets, medium dogs (26 – 45 lbs) has two tablets, and the box for larger dogs (45 lbs and up) also contains two tablets. Because of its flavor, pet owners say that the product is easy to administer to their dogs.

The tablets contain Praziquantel, Pyrantel Pamoate, and Febantel that are all effective in treating tape, round, hook, and whipworms. What’s nice about this brand is that it could already work on intestinal parasites with just a single dose.

Here are the types of worms that this product gets rid of:

  • Tapeworms: Dipylidium Caninum and Taenia Pisiformis
  • Hookworms: Ancylostoma Caninum and Uncinaria Stenocephala
  • Roundworms: Toxocara Canis and Toxascaris Leonina
  • Whipworms: Trichuris Vulpis

This product from Bayer is considered to be on the high end of the price spectrum of dog dewormers.

Pet owners who purchased this product didn’t like the included instructions on the package as they don’t include the dosage frequency.

When it comes to the possible side effects, your dog may get diarrhea. Some pet owners also reported vomiting and lethargy.



4. Nemex 2 by Pfizer

This dog dewormer by Pfizer comes in liquid form or suspension, so it’s important for you to shake this well before using on your dogs. When it comes to the taste, this syrup is caramel-flavored which makes it palatable to canines.

This is products should only be used on dogs or puppies that are at least two weeks old. It is suggested that you give your dog a teaspoon per 10 lbs of body weight.

Nemex 2 comes in 2 or 16 ounces. One ml of this syrup contains 4.54 mg of Pyrantel Pamoate which is effective when it comes to treating different types of worms; specifically the following:

  • Roundworms: Toxascaris Leonina and Toxocara Canis
  • Hookworms: Ancylostoma Caninum and Uncinaria Stenocephala

As you can tell, this doesn’t treat any tapeworms so it’s best to confirm with a vet first what type of worms your dog is infested with. If tapeworms are present, you should consider a different product.

This dewormer showed no toxic effects on pregnant and nursing dogs, but it’s still best to treat bitches with this at least two to three weeks after whelping or giving birth.

Pet owners who purchased this did not like that the package comes with no instructions. Some of the buyers of this product also find this effective in treating their cats.



3. Sentry Pet Care HC WormX Plus Dog Dewormer

Sentry Pet Care dewormer comes as a flavored chewable tablet, though the flavor itself is not indicated on the box or even on Sentry’s website. You can purchase this dewormer for puppies and small dogs, medium-sized, and large dogs that weigh more than 25 lbs.

This is only recommended for dogs that are 12 weeks and older. The tablets have 114 mg of Pyrantel Pamoate and 114 mg of Praziquantel that are also found in vet brands and are found effective when treating intestinal parasites like the following:

  • Tapeworms: Dipylidium Caninum and Taenia Pisiformis
  • Roundworms: Toxocara Canis and Toxascaris Leonina
  • Hookworms: Ancylostoma Caninum, Ancylostoma Braziliense, and Uncinaria Stenocephala

This dewormer should only be used on your pet once a month and is considered as a quick and effective way to kill most worms that your dog has.

Some pet owners claim that they already got the results 24 hours after using this dewormer. Although some users shared that the instructions included in this package don’t include the frequency and dosage.

The suggested dosage for your dog is 2.27mg per lb. of your dog’s body weight. When it comes to breeding dogs and pregnant bitches, whether this product is safe for them or not is still undetermined.

Possible side effects may include diarrhea, vomiting, and presence of some mucus in your dog’s waste.



2. 8-in-1 Safe-Guard Canine Dewormer

8in1 Safe-Guard Canine Dewormer for Large Dogs, 3 Day Treatment (packaging may vary)

3,122 Reviews

This broad-spectrum dewormer from Safe-Guard comes in powder form. This is a dog dewormer that should be used as a treatment for three consecutive days so that you’ll get the best results.

This should only be used on dogs or puppies that are 6 weeks and older.

It is available in small, medium, 2-pack medium, and large packets, so this could treat all sizes of dogs – even large dogs that are at least 40 lbs. One gram of this product should be given for every 10 lbs. of your dog’s body weight.

Since this comes in powdered form, you can easily have this mixed in your pet’s food. However, if your dog’s food is dry, it will require a bit of moisture so that it will be evenly mixed.

Safe-Guard dewormer product contains 222 mg of Fenbendazole in every gram and can treat the following types of worms:

  • Tapeworms: Taenia Pisiformis
  • Roundworms: Toxocara Canis and Toxascaris Leonina
  • Hookworms: Ancylostoma Caninum and Uncinaria Stenocephala
  • Whipworms: Trichuris Vulpis

Clinical studies rolled out for this product reported that only about 1% of the dogs tested have manifested some side effect symptoms like vomiting and runny stools. It’s not a bad number considering that it’s only three out of the 240 dogs that showed these adverse effects.

Some pet owners didn’t like that it only treats one type of tapeworm which is not really the most common when it comes to dogs in the US. Some also said that the flavor of this product is not really appealing to their pets.

But regardless, with its price range, it is already a great buy.



1. Panacur C Canine Dewormer

We list this Panacur C Canine Dewormer as the top dog dewormer because of its efficacy when it comes to treating your dog’s intestinal parasites. Like Safe-Guard’s dewormer, this also comes in powder form which makes it easy to mix with your dog’s food.

This should only be used on dogs or puppies that are six weeks and above. You can choose to get this in 1g, 2g, and 4g packets.

The dosage will also depend on your dog’s weight, and so 1 gram is good for every 10 lbs. of your dog’s body weight. For the treatment to be effective, your dog should be given the right dosage for three consecutive days.

This is good to use for dogs of all sizes – even on dogs that are heavier than 80 lbs. You’ll just have to get multiple packets to ensure appropriate dosage.

Since this is an affordable dewormer, it won’t even be too expensive to treat a large dog with multiple packets.

Panacur C contains Fenbendazole which is a component that’s present in most vet products that work on different types of worms such as the following:

  • Tapeworms: Taenia Pisiformis
  • Roundworms: Toxocara Canis and Toxascaris Leonina
  • Hookworms: Ancylostoma Caninum and Uncinaria Stenocephala
  • Whipworms: Trichuris Vulpis

You may have noticed that Panacur C treats the same worms as Safe-Guard’s dewormer. But what makes this different from Safe-Guard is that some vets use this product to treat other parasites like Giardia. Pet owners also attest to this.

This is also safe to be used on breeding and pregnant bitches, according to clinical studies. Interestingly, possible side effects only affected about 1% of 240 dogs that are tested – similar to the test result conducted for Safe-Guard. Only 3 out of the 240 dogs tested manifested side effects like vomiting, lethargy, and diarrhea.

Some pet owners are not really happy about how this only treats one type of tapeworm, although this is already something that’s on the label. That said, this isn’t for you if your dog is diagnosed with another kind of tapeworm aside from Taenia Pisiformis.

There are also pet owners who had a hard time feeding this to their dogs because they claim that their pets seem to not like its taste and flavor. For some, however, they find mixing this with food like squash and regular dog food to be an effective way for their dog to ignore its taste.



Buyer’s Guide – Dog Dewormers

If you feel like you’re a bad fur parent because your dog has worms, you shouldn’t! This is something common to happen, as dogs are just really prone to this. This is the very reason why vets would suggest getting your dog checked once or twice a year.

Humans can also be infested by roundworms and hookworms. These two are definitely on the list of the most common type of worms that dogs in the US could have – with tapeworms as the most common.

All of these could be acquired by your dog through licking or eating them directly from soil or different surfaces. Some types of worms could also be acquired if your dog ate its own feces or ate raw meat or fish.

There are plenty of dog dewormers out there that you can easily use to treat your dog even without any prescription from the vet. The ones listed above are what we found best but do keep in mind that the best will really vary depending on what your dog really needs.

Before purchasing any dewormer, it’s best to have your dog tested to check if deworming is really needed in the first place. Deworming your dog if it’s not necessary may just cause harm.

Aside from that, knowing what specific types of worms your dog has will make it easier for you to choose the best product to get.

If in case you find and think that any of the dog dewormers listed above do not meet your dog’s needs, we’re still here to help! Here are the things you should consider when it comes to purchasing a dog dewormer:

  • Budget – This is very important, especially if you’re trying to treat a medium or large dog. Bigger dogs will usually require higher dosages of deworming products, and so always make sure that your budget can accommodate the expenditures.
  • Features – Once you know what type of worms your dog has, then the features of the dewormer is definitely something you should be focused on. You need to check if that specific brand will work on the type of worm that your dog has.

The last thing you want is to complain about how the product isn’t effective when in the first place; the manufacturer didn’t really claim that the product could treat a specific type of worm.

  • Dog Size – You need to check if the brand you’re looking at can work well on your dog based on its size. There are brands that only claim to work on small dogs or puppies and so this is something you have to really check out first.
  • The frequency of Dosage – There are dewormers that would really require some of your time during the course of the treatment, and so it’s best to choose what would work with your schedule.

If you’re someone who can’t commit your time to ensure that the frequency of dosages is followed for the next three to seven days, then dewormers that only require one dosage to fix the problem is what will suit you. But remember, this is not really something you can just decide by yourself.

  • Efficacy – It pays to check for the reviews of different pet owners to know how well the specific brand you’re looking at has worked on their pets. Of course, manufacturers can easily claim that their product will work well on a specific type of worm, but the ones who have actually tried the product can really attest if it’s true or not.
  • FDA Approval – Always check if the product is FDA-approved to be assured that it is safe. You can always call its hotline to check for the approval status of a product.
