    Imagine lots of spooky creatures crawling inside your beloved dog’s intestines.

    Ugh!!! That’s disgusting.

    Who would like feeding and raising mobs of creepy worms causing serious harm to their precious pooch?

    Simply, no one!

    Dogs have a habit of eating anything from anywhere. They will eat your dinner leftovers. They will eat rotten food from dustbins, and you might have noticed them eating other dogs’ poops.

    That’s awful for you, not for your dog.

    Resultantly, they get harmful intestinal worms. There’s no limitation. Dogs of all ages can get contracted with intestinal parasites.

    Some kinds of worms can be seen with the naked eye, while some can’t be.

    So, there’s a chance you might not get aware that your dog is contracted with worms at once. In that case, you can get help from your vet.

    Once you sense any signs of your dog being infected with intestinal parasites, examine the worm type, and take steps for parasitic elimination.

    Now, what can you do to keep your dog happy and healthy?

    No need to restrict your dog’s outdoor activities. You only need a dewormer specifically created for dogs. When you know the worm type affecting your dog, picking up the best dog dewormer becomes easier.

    Best Top Dog Dewormers: Our Top Picks

    Before we check the details of  the best dewormers for dogs, you must know what exactly are dog worms?

    Let’s find out.

    What Are Dog Worms?

    5 BEST DEWORMER FOR DOGS - How to deworm a dog (10)

    Worms, also called helminths, are parasites that usually enter the body of a host and are capable of living and feeding off the host they have entered in.

    There are many kinds of dog intestinal worms, usually divided into four common types:

    1. Roundworms
    2. Hookworms
    3. Whipworms
    4. Tapeworms

    All these worm types cause serious health dangers to dog’s health, but roundworms are the most dangerous of all types. Plus, these intestinal worms have their further species.

    1. Roundworms:

    The two species of roundworms are Toxocara canis and Toxascaris leonina. Both of them are long, white, and spaghetti-like in appearance.

    Initially, the roundworm larvae infect the dog’s intestinal tract. Later on, they can move to other body tissues and organs. When, as Toxocara canis, a roundworm larva matures, it moves to the lungs and then up to the airway. Afterward, it re-enters the intestine to complete its lifecycle.

    On the other hand, Toxascaris leonina has a simpler lifecycle and doesn’t move.

    Roundworms are diagnosed with a stool sample. If left untreated, they can be the cause of poor growth or, in severe conditions, can lead to death.

    2. Hookworms

    Hookworms are very short, typically 1/8 of an inch. They are blood-sucking parasites and suck heavy amounts of blood from the intestine of their host dog. They can cause anemia in dogs and can be fatal if not treated.

    Just like Toxocara canis, hookworms also move about in their host’s body, enter the lungs, and then re-enter the intestine to grow mature.

    Hookworms can only be detected microscopically through a stool test called ‘Fecal Flotation’

    3. Whipworms

    Whipworms are large intestinal parasites. They live in the cecum – the beginning of the large intestine. Hookworms don’t suck as many nutrients as other types of worms do.

    In mild cases, they don’t cause any symptoms. But, if they make their way to intestinal tissues, they can be fatal and cause inflammation, weight loss, diarrhea, and sometimes anemia.

    Vets can diagnose whipworms through the fecal sample. Whipworm eggs are not easy to find, though. Therefore, repeated fecal exams are recommended.

    4. Tapeworms

    Tapeworms are small intestinal parasites. They are long (half a foot or more in length), flat, and segmented.

    Tapeworms suck blood from the walls of the small intestine and extract nutrients. They don’t cause any serious harm until and unless the host dog is extremely active. When excreted, tapeworms pass on their segments in the affected dog’s stool.

    Mostly, they are visible in a dog’s poop and look like little pieces of rice.

    If you notice some of them in your dog’s poop or find him scooting his bottom along the ground, take your dog’s stool sample to a vet for diagnosis.

    How Do You Know If A Dog Has Worms?

    5 BEST DEWORMER FOR DOGS - How to deworm a dog (5)

    As a dog owner, you must be aware of the signs showing that your dog is contracted with parasitic worms. Though, the symptoms of each type of worm vary depending upon how the dog got affected.

    Tapeworms, hookworms, and whipworms, if not present in large numbers, don’t cause major health threats. However, sometimes roundworms can make dogs seriously ill.

    Parasitic worms, other than tapeworms, are rarely seen. And, you cannot tell if your dog is contracted by worms or not, just by looking.

    The only way to help is, check their poop and get it microscopically tested.

    However, the general symptoms of intestinal worms in dogs can include:

    1. Diarrhea
    2. Lethargy
    3. Cough ( in case of roundworm and hookworm infections)
    4. Vomiting
    5. Nutritional deficiencies
    6. Blocked intestine (in severe cases infestations)
    7. Bloody stool (can be bright red or dark purple)
    8. Swollen abdomen
    9. Abdominal pain
    10. Dehydration
    11. Intestinal blockage or Pneumonia ( in serious cases of roundworm)
    12. Poor coat appearance
    13. Unexplained weight loss
    14. Increased appetite

    If you see any of these signs in your dog, take his stool sample for microscopic examination and start the treatment instantly. Early treatment can save your dog from drastic health threats and prevent the worm from spreading.

    Even if you don’t notice any such signs in your dog, a better and wise action is to get your pooch’s poop annually diagnosed.

    How Can Dogs Catch Parasitic Worms?

    5 BEST DEWORMER FOR DOGS - How to deworm a dog (4)

    Dogs can pick up parasitic worms in different ways. Some of the most common ways for dogs to get infected by worms are as follows:

    1. From Mother Dog

    Roundworms and hookworms can creep into the womb of the mother dog. Therefore, they can be transmitted to unborn puppies. Resultantly, the puppies are born with parasitic worm issues.

    The other way a mother dog passes on her worms to young puppies is through lactation.

    2. Swallowing Contaminated Soil

    Another major source of getting parasitic worm infections for dogs is ingesting contaminated soil. Most of the roundworms, whipworms, and hookworms are found in contaminated soil.

    Dogs get the infection while ingesting and grooming their fur with dirty soil. Keeping your dog clean can reduce the risk of getting infected.

    3. Walking On Contaminated Soil

    By walking on contaminated soil, your pet can pick up hookworms (they can penetrate through the skin) through the skin areas touching the infected soil, such as paws and the belly.

    4. Consuming Other Infected Animals

    Dogs can grab all four types of intestinal worms by eating any worm-infected animal, rodent, for example. The carcass of dead domestic animals, like, sheep can also contain harmful parasitic worms.

    5. Fleas

    The only intestinal worms that can be transferred through fleas are tapeworms. In fact, this is the only way they can be contracted with a dog. If your dog eats a tapeworm-infected flea, he will get infected.

    5 BEST DEWORMER FOR DOGS - How to deworm a dog (8)

    De-wormers come in many different formations, such as chew tablets, powdered form, granule form, or liquid form. Also, there are different types of de-wormers available for large breeds, small breeds, and puppies.


    Almost all the types of worms reside in the intestinal tract of their host dog. In contrast, some of the worm types like tapeworms, hookworms, and roundworms target the stomach.


    A de-wormer either diffuses the worm or makes it weaker and causes it to excrete its sucker through the intestinal tract in the dog's poop.


    But the treatment cannot kill the parasitic eggs or larvae. So, the treatment is carried on up until the eggs hatch, larvae get mature, and are completely eliminated.

    Most of the de-wormers take two to three weeks to work. However, de-worming time can depend upon the intensity of infestation and the quality of the de-wormer.

    Choosing the right de-wormer out of so many available in the pet market is a daunting task. If you do a proper investigation of the type of worm your dog is infected with, first, picking one best dog de-wormer becomes way easier.


    Simply put, a dog de-wormer specifically formulated to kill roundworms will be useless in the treatment of tapeworm or hookworm. Makes sense?


    A right dog de-wormer is the one that is suitable according to your pet’s specific worm infection type and does its job effectively and efficiently.


    Luckily, most of the de-wormers are broad-spectrum products. They are also effective in treating multiple types of parasites and their further strains.

    • De-worm your dog every two weeks until he is 12 weeks of age.
    • After 12-weeks, de-worm him monthly until he reaches six months of age.
    • From six-month and above, every dog needs de-worming every three months (for better protection against intestinal worms).

    Here is what you can expect after de-worming your dog:


    • The first hours of de-worming: Most of the de-wormers start working instantly.
      But, make sure your dog completely ingests the de-worming chew tablets or powder-based medicine. Some dogs try spitting the medicine immediately or throw up after taking the dosage.
      If any such thing happens, ask your vet for advice.
    • De-worming after a few days: After a few days, you'll notice a visible reduction in worm extraction in your dog's stool and an improvement in his health.


    If you see any unexpected changes in your pet’s condition by following the treatment, consult your vet right away.

    You can opt for over-the-counter non-prescription de-wormers. They are highly effective, easy to administer, and have no side effects.

    Other ways to de-worm your dog by yourself are some natural and proven home remedies. Such as:


    • Pumpkin seeds
    • Chamomile
    • Turmeric
    • Apple cider vinegar
    • Carrots
    • Coconut

    NEVER!!! Worms in dogs never go away on their own. However, some dogs can develop immunity against infections and live a happy life. But this is not the case for every dog out there.

    Dogs will need some kind of medical assistance or de-worming to get rid of the worms. Else, untreated dogs can experience serious ailments, lethargy, damage to internal organs, or death.

    So, medical treatment or at-home de-worming is a MUST!
