10 Best Dewormers For Puppies in 2026

This post contains affiliate links. As an Amazon Associate, we earn from qualifying purchases.

The best overall dewormer for puppies is the PetArmor Sure Shot Liquid Dewormer, a vet-quality liquid that is safe for puppies as young as two weeks old and targets four species of worms. For a broad-spectrum option that covers whipworms, the Panacur C Canine Dewormer Packets are a top choice, while the Elanco Tapeworm Dewormer Tablets are the go-to for confirmed tapeworm infections.

Bringing a new puppy home comes with a lot of joy and a few less-glamorous realities. One of the most important is deworming. Puppies are incredibly susceptible to worms, often contracting them from their mother, and an untreated infestation can affect their growth and health.

This guide is built from a close look at product specifications, manufacturer guidelines, and patterns in owner feedback. We’ve focused on what matters most for puppies: safety from a young age, ease of administration, and the range of worms covered. Our goal is to help you pick the right treatment with confidence.

The Best Dewormers For Puppies, Reviewed

#1Best Overall

PetArmor Sure Shot Liquid Dewormer

PetArmor Sure Shot Liquid Dewormer
Worms Removed4 species
Safe AgePuppies 2 weeks+
Dosing1 tsp per 10 lbs
Treatment SchedulePuppies: 2-10 weeks
Check Latest Price →

What We Like

  • Removes 4 species of worms
  • Safe for puppies 2 weeks and older
  • Vet-quality liquid formula

Trade-offs

  • Only targets roundworms and hookworms, not tapeworms
  • Requires multiple doses for puppies up to 10 weeks

A dosing schedule that starts at just 2 weeks old makes this one of the earliest safe options for puppies, which matters because roundworms can be passed from mother to pup before birth. The liquid formula measures out precisely at one teaspoon per ten pounds of body weight, so you’re not guessing or breaking tablets.

The trade-off is that this dewormer only covers roundworms and hookworms. If you’re dealing with tapeworms, you’ll need a separate product like the Elanco Tapeworm Dewormer Tablets, which handles that specific type. That said, for a puppy’s first few months, roundworms and hookworms are the most common threats, and the early start age here is two weeks, compared to the six-week minimum on something like the OZIPCO Fenbendazole Liquid. The multiple-dose schedule through week ten takes a little planning, but the dosing is straightforward.

Best for: Puppy owners who want a liquid dewormer safe from two weeks old that covers roundworms and hookworms without guesswork. Not ideal for households dealing with tapeworms, since this product doesn't address them.
#2Best Broad Spectrum

Panacur C Canine Dewormer Packets

Panacur C Canine Dewormer Packets
Parasites CoveredRoundworms, hookworms, whipworms, tapeworms
Age Minimum6 weeks
Dosage1 packet per 10 lbs
FormPowder packets
Check Latest Price →

What We Like

  • Treats four types of worms
  • Safe for pregnant dams
  • Suitable for puppies 6 weeks+
  • Easy-to-dose powder packets

Trade-offs

  • Each packet only covers 10 lbs of dog
  • Must be given for multiple days per label

Panacur C covers roundworms, hookworms, and whipworms, so you don’t have to guess which worm your puppy picked up. That breadth makes this packet a practical first-line choice for anyone who wants one product that handles the most common intestinal parasites. The powder mixes into food, which is a lot easier than prying a puppy’s mouth open for a liquid or tablet. It’s safe for pregnant dams too, so if you’re dealing with a litter, you can treat the mother without worry.

Each packet treats only ten pounds, so a growing puppy or a larger breed will need multiple packets per dose, and the full course runs several days. Compared to the Elanco Tapeworm Dewormer Tablets, which only target tapeworms and start at four weeks of age, Panacur C covers roundworms, hookworms, and whipworms but requires a longer treatment window. If you want a single-dose solution for a specific worm, that tablet is faster. But if you want broad coverage of roundworms, hookworms, and whipworms and don’t mind the multi-day routine, this packet is the more complete option for those three types.

Best for: Puppy owners who want one dewormer that covers roundworms, hookworms, and whipworms and prefer a powder they can mix into food. Not ideal for those who want a single-dose treatment or need a product for puppies under six weeks old.
#3Best For Tapeworms

Elanco Tapeworm Dewormer Tablets

Elanco Tapeworm Dewormer Tablets
Active IngredientPraziquantel
Target ParasitesDipylidium caninum, Taenia pisiformis
Age Minimum4 weeks and older
Dosage FormTablets (can be crumbled)
Count5 tablets per bottle
Check Latest Price →

What We Like

  • Targets two common tapeworm species
  • Safe for puppies from 4 weeks old
  • Tablets can be crumbled into food
  • Single-ingredient formula for tapeworms only

Trade-offs

  • Treats tapeworms only, not roundworms or hookworms
  • Not chewable; must be crumbled or given whole

Praziquantel is the standard active ingredient for tapeworms, and this 5-count bottle delivers it in a straightforward tablet that can be crumbled into food for puppies as young as 4 weeks. If tapeworms are the specific problem, common from fleas or prey exposure, this is the cleanest solution in the guide for that single job.

This tapeworm dewormer targets only two specific tapeworms. Dipylidium caninum and Taenia pisiformis, so if your dog has a confirmed tapeworm infection, you get exactly the medicine needed without extra ingredients. Because it doesn’t treat roundworms or hookworms, owners often pair it with a broader dewormer for general parasite control.

Best for: Puppies 4 weeks and older with confirmed tapeworm infections. Not ideal for general deworming against multiple worm types.
#4Best Granule Formula

SAFE-GUARD Canine Dewormer Granules

SAFE-GUARD Canine Dewormer Granules
Worms treatedTapeworms, Roundworms, Hookworms, Whipworms
FormGranules mix into food
Age minimumPuppies 6 weeks and older
Course length3 consecutive days
Protection duration6 months
Check Latest Price →

What We Like

  • Treats four major worm types
  • Easy-to-feed granules mix with food
  • Safe for puppies over 6 weeks
  • Safe for pregnant and heartworm-infected dogs

Trade-offs

  • Requires 3-day administration, not a single dose
  • Granules must be mixed with food each day

Three consecutive days of granules mixed into food covers tapeworms, roundworms, hookworms, and whipworms in a single course. That broad spectrum makes it a practical choice for a puppy that might have picked up more than one type of worm. The granules are easy to hide in a meal without a fight. It also works for pregnant dogs and those with heartworm, which avoids the worry of switching products if your dog’s situation is complicated.

This dewormer requires three consecutive days of treatment, which means you need to plan ahead rather than giving a single dose. Owners who can stick to a three-day routine get coverage against tapeworms, roundworms, hookworms, and whipworms all from one product. The granules mix into food, so for most dogs mealtime becomes medicine time without a fight.

Best for: Puppy owners who want a broad-spectrum wormer that mixes easily into food and covers multiple worm types with one three-day course.
#5Best Chewable For Small Dogs

Elanco Chewable Quad Dewormer

Elanco Chewable Quad Dewormer
FormBeef-flavored chewable tablet
Weight range2-25 lbs
Worms coveredTapeworms, roundworms, hookworms, whipworms
Minimum age4 weeks
Count4 tablets
Check Latest Price →

What We Like

  • Beef-flavored chewable for easy dosing
  • Broad-spectrum against four worm types
  • Suitable for puppies as young as 4 weeks
  • Designed for small dogs 2-25 lbs

Trade-offs

  • Only 4 tablets per pack limits multi-dose treatments
  • Not suitable for dogs under 4 weeks of age

Four worm types in a single beef-flavored chewable means you only need one product to cover tapeworms, roundworms, hookworms, and whipworms in small dogs. That broad spectrum is the main reason this tablet works for puppies starting at four weeks and up to 25 pounds. That covers most small-breed puppies without needing to measure liquid or mix powder into food. The chewable design makes it simpler than pilling a dog that already feels off, and the beef flavor helps mask the medicine taste.

The four-tablet count means you get exactly four doses in the pack. If you have more than one small dog or need to repeat the treatment, you will need to buy another pack. Other dewormers in this guide, such as the PetArmor Sure Shot Liquid, come in a 2 oz bottle that can treat multiple dogs or provide follow-up doses. But that product covers only roundworms and hookworms, not the full spectrum this chewable offers. For a single puppy in the 2-25 lb range, one pack gives you a complete broad-spectrum dose without measuring or mixing.

Best for: Owners of small-breed puppies who want a single, easy-to-give chewable that covers four common worm types. Not ideal for households needing multiple doses or treating larger dogs.
#6Best Liquid With Syringe

OZIPCO Fenbendazole Liquid Dewormer

OZIPCO Fenbendazole Liquid Dewormer
Active IngredientFenbendazole
Worm Coverage4 types: round, hook, whip, tape
Age Minimum6 weeks and older
Dosage MethodSyringe or mix into food
Bottle Size100 mL
Check Latest Price →

What We Like

  • Broad-spectrum coverage for four common worms
  • Liquid form with included dosing syringe
  • Can be mixed into wet or dry food
  • Suitable for puppies from 6 weeks old

Trade-offs

  • Requires shaking before each use for proper dosing
  • Must follow body-weight chart and course length exactly
  • Not a single-dose treatment, needs full course per label

A 100 mL bottle of fenbendazole liquid means you can treat a single dog through a full course or cover multiple dogs in a multi-pet home without buying a new bottle every week. The liquid form mixes straight into food or goes in by syringe, so there is no wrestling with pills. It covers roundworms, hookworms, whipworms, and tapeworms, which is the full set of common intestinal worms listed on the label. It works from six weeks of age, so it fits puppies at that minimum age.

You have to dose by body weight using the chart on the label and stick to the full course length, which means a little more attention than a single-dose product. If you prefer a pre-measured packet that dissolves without a syringe, the Panacur C granules are simpler, but they treat only one weight class per packet. For anyone who wants broad-spectrum coverage in a flexible liquid that works for picky eaters and multiple dogs, this syringe-and-bottle setup is a practical option.

Best for: Owners of puppies six weeks and older who need broad-spectrum worm coverage and want a liquid that can be hidden in food or given directly by syringe. Not ideal for someone who wants a single-dose tablet or a packet they can just sprinkle on once.

#7Best For Puppies

Pfizer Nemex-2 Wormer

Pfizer Nemex-2 Wormer
Active ingredient4.54 mg pyrantel pamoate per ml
Target parasitesLarge roundworms and hookworms
Puppy safetySafe for puppies
FormLiquid
Size2 oz
Check Latest Price →

What We Like

  • Safe for puppies
  • Controls large roundworms and hookworms
  • Palatable liquid formula
  • Convenient ready-to-use design

Trade-offs

  • Only targets two worm types, not tapeworms or whipworms
  • Only targets roundworms and hookworms, not tapeworms or whipworms

A 2 oz liquid with 4.54 mg pyrantel pamoate per ml means this is a targeted treatment for the two most common puppy worms, large roundworms and hookworms, without overcomplicating things. That focus makes it a straightforward choice for new puppy owners who want a dewormer they can trust from the start, especially since the label explicitly states it’s safe for puppies. There’s no guesswork about dosage or mixing, just a palatable liquid that most pups will take without a fight.

Nemex-2 doesn’t cover tapeworms or whipworms, so if your puppy has a broader infestation, you’ll need a different product like Panacur C Canine Dewormer Packets, which treats multiple worm types. But for a first-line defense against the worms puppies most often pick up from their mother or environment, this liquid’s simplicity and safety profile are hard to beat. It’s a no-fuss tool for the job it’s designed to do.

Best for: Puppy owners wanting a safe, simple liquid dewormer that targets roundworms and hookworms. Not ideal for dogs needing tapeworm or whipworm coverage.

#8Best For All Sizes

Lumaho Liquid Dog Dewormer

Lumaho Liquid Dog Dewormer
FormatLiquid
Worm TypesTapeworm, whipworm, hookworm, ascarids
Weight Range5-200 lbs
Volume3.38 fl oz
DosingWeight-based
Check Latest Price →

What We Like

  • Covers tapeworm, whipworm, hookworm, ascarids
  • Liquid format avoids splitting pills
  • Weight-based dosing for 5-200 lbs
  • Generous 3.38 fl oz bottle

Trade-offs

  • Requires follow-up weekly then every 2-3 months

A single 3.38-ounce bottle covers dogs from 5 to 200 pounds, which means one purchase handles everything from a new Chihuahua puppy to an adult Great Dane. The liquid format lets you measure the exact dose by weight instead of guessing which tablet size or fraction to use, and it skips the wrestling match that often comes with pilling a reluctant dog. Because it targets tapeworm, whipworm, hookworm, and ascarids, you aren’t left wondering whether you picked the wrong spectrum for the worms your pup actually has.

The Lumaho Liquid Dog Dewormer covers tapeworm, whipworm, hookworm, and ascarids, making it a broad-spectrum option that treats more worm types than a tapeworm-only tablet like Elanco’s. You start with an initial serving, follow up a week later, then repeat every two to three months. That schedule means more calendar reminders than a single-dose product. But the liquid format lets you adjust the dose by your dog’s weight, which is handy for multi-dog households or owners raising a puppy through different sizes.

Best for: Households with multiple dogs of different sizes or a single growing puppy, where weight-based liquid dosing and broad-spectrum coverage matter more than a one-time pill. Not ideal for owners who prefer a quick chewable tablet and don't want to track a multi-step follow-up schedule.

#9Best Dual-Active Formula

LanoDur Dual-Active Liquid Dewormer

LanoDur Dual-Active Liquid Dewormer
Active IngredientsPyrantel Pamoate & Praziquantel
Target WormsTapeworms, Roundworms, Hookworms
FormLiquid oral suspension
Dosing ToolMeasuring syringe included
Bottle Size150 mL (5 fl oz)
Check Latest Price →

What We Like

  • Dual-active formula covers three worm types
  • Liquid format for tablet-resistant dogs
  • Measuring syringe ensures accurate dosing
  • Convenient 150 mL bottle for multiple doses

Trade-offs

  • Does not treat whipworms
  • Requires shaking before every use
  • Must ensure full dose is swallowed

A combination of praziquantel and pyrantel pamoate means this liquid covers tapeworms, roundworms, and hookworms in one dose. The included measuring syringe takes the guesswork out of dosing by weight, and the 150 mL bottle provides a generous supply for dogs of different sizes. It suits owners who want broad coverage without wrestling a pill into a reluctant mouth.

If whipworms are a concern, this dewormer won’t help, it treats tapeworms, roundworms, and hookworms only. The dual-active liquid covers those three types in a single dose, while PetArmor Sure Shot targets just roundworms and hookworms. Shake the bottle well before each use, and ensure the dog swallows the full measured amount, whether given directly or mixed with a small portion of food.

Best for: Dog owners who want broad-spectrum worm coverage in a liquid form that avoids tablet struggles. Not ideal for treating whipworms.

#10Best For Small Dogs & Puppies

FLIKO 3-Way Dewormer Tablets

FLIKO 3-Way Dewormer Tablets
Target ParasitesTapeworms, Roundworms, Hookworms
Weight Minimum6 lbs
Tablet Count100 Tablets
Made InUSA
Check Latest Price →

What We Like

  • Covers three common worm types
  • Safe for puppies and kittens 6 lb+
  • 100 tablets per bottle

Trade-offs

  • No coverage for whipworms
  • Tablet form requires pet to swallow a pill

A dose of this dewormer delivers 30 mg of pyrantel pamoate and 30 mg of praziquantel, targeting tapeworms, roundworms, and hookworms in one go. That broad coverage makes it a practical first-line choice for a new puppy owner who wants to handle the most common intestinal invaders without juggling multiple bottles. The formula works for dogs and cats as light as 6 pounds, so it fits tiny breeds and young pups. The 100-count bottle also provides enough tablets for multiple small pets or repeated treatments as needed.

This is a tablet, not a liquid or a pour-on, so you may need to get creative if your puppy is a master at spitting out pills. Compared to the PetArmor Sure Shot liquid, which works for puppies starting at two weeks, the FLIKO tablets require your pup to be at least 6 pounds. That said, the FLIKO covers tapeworms and comes from a US-based manufacturer, so you’re not guessing about quality standards. For a small-dog household looking for a straightforward, broad-spectrum tablet, this is a clean fit.

Best for: Puppy owners who want a dewormer that targets tapeworms, roundworms, and hookworms for small dogs 6 lb and up. Not ideal for puppies under 6 lb or those that cannot swallow tablets.

How We Evaluated Dewormers For Puppies

This evaluation is research-based, drawing on manufacturer documentation, veterinary guidelines, and the collective experience of dog owners. Specs, ingredient lists, and reported outcomes were analyzed to identify the options that offer reliable and safe treatment.

The most critical criteria for this category were safety for young puppies, the types of worms treated, and ease of administration. A dewormer is only useful if you can get your puppy to take it, and it must be effective against the parasites most common in young dogs. We also considered the dosing schedule, as some treatments require multiple days of administration.

A research-led evaluation has limits. We cannot account for every unique puppy’s health status or the specific strain of a parasite in your area. The best approach is to use this guide to find a strong candidate, then confirm with your vet that it’s appropriate for your puppy’s age, weight, and specific needs.

What To Look For In Dewormers For Puppies

Choosing a dewormer for a puppy is different than treating an adult dog. You need a product that is safe for a developing system and effective against the specific worms a puppy is most likely to carry.

Look for a dewormer that targets roundworms and hookworms at a minimum, is safe for your puppy’s age, and comes in a form you can easily administer. Check the label for the minimum age and weight requirements.

Age and Weight Minimums

The most important safety check is the minimum age and weight on the label. Some dewormers are safe for puppies as young as two weeks old (like our best overall pick), while others require the puppy to be six weeks or older. Giving a dewormer too early can be ineffective or even dangerous. Always weigh your puppy accurately before dosing.

Worm Spectrum: What Does It Kill?

Puppies most commonly get roundworms and hookworms from their mother. A good first dewormer should at least cover these two. If you see rice-like segments in your puppy’s stool or around their rear, you are dealing with tapeworms and need a product that specifically targets them. Whipworms are less common in very young puppies but are still a concern. Understanding what you are treating is the first step to choosing the right product.

Form: Liquid, Tablet, or Granule

The best form is the one your puppy will actually take. Liquids (like the PetArmor Sure Shot) are great for very young puppies and can be given directly with a syringe or mixed into food. Tablets can be crumbled, but some puppies are experts at eating around them. Granules and powders, like the Panacur C packets, are designed to be mixed into a meal, making them a low-stress option for picky eaters.

  • Check the label for the specific worms the product treats, not just “broad-spectrum.”
  • Verify the minimum age and weight of your puppy before buying any dewormer.
  • Look for a dosing syringe or measuring tool if you choose a liquid dewormer.
  • If your puppy has a known tapeworm infection, buy a product that lists tapeworms on the label.
  • Talk to your vet if your puppy has a heavy worm burden or is not thriving.

A good rule of thumb is to start with a dewormer that covers roundworms and hookworms, then follow up with a broader treatment or a specific tapeworm dewormer as needed.

Frequently Asked Questions

How often should I deworm my puppy?

Most puppies need to be dewormed every two to three weeks until they are several weeks old, then monthly until they are six months old. This schedule is based on the life cycle of common worms. Always follow the dosing schedule on the label of your chosen dewormer and your vet’s advice.

Can I use an over-the-counter dewormer instead of going to the vet?

Yes, many effective over-the-counter dewormers are available. They are a good option for routine deworming. However, if your puppy has a heavy infestation, is vomiting, has diarrhea, or is not gaining weight, a vet visit is necessary for a proper diagnosis and treatment plan.

What is the difference between a dewormer and a heartworm preventative?

Dewormers treat intestinal parasites like roundworms, hookworms, and tapeworms. Heartworm prevention is a separate medication that prevents a life-threatening parasite transmitted by mosquitoes. Some combined products exist, but they are usually for adult dogs. A puppy needs both a deworming schedule and a separate heartworm preventative.

My puppy has tapeworms. What is the best medicine?

The best medicine for tapeworms in puppies is one that contains praziquantel as the active ingredient. The Elanco Tapeworm Dewormer Tablets, our pick for best for tapeworms, is safe for puppies from four weeks old and targets the two most common species. Tapeworms require a specific medication, so a general dewormer will not work.

How do I safely deworm my puppy at home?

The deworming process starts with weighing your puppy accurately. Then, read the label to confirm the dose and the minimum age requirement. For liquids, use the included syringe to squirt it into the side of the puppy’s mouth. For powders, mix the full packet into a small amount of wet food and ensure the puppy eats it all.

The Bottom Line

For most puppy owners, the PetArmor Sure Shot Liquid Dewormer is the best starting point. It is safe from two weeks old, easy to dose, and covers the two most common puppy worms. It is a simple, reliable choice that every new puppy owner should have on hand.

If your puppy is six weeks or older and you want a single product that covers four worm types including whipworms, the Panacur C Canine Dewormer Packets are an excellent broad-spectrum option. For a confirmed tapeworm infection, skip the general dewormers and go straight to the Elanco Tapeworm Dewormer Tablets.

The single most important factor is choosing a dewormer that is safe for your puppy’s exact age and weight. Read the label, measure carefully, and stick to the recommended schedule to give your puppy a healthy start.
