Signs and Symptoms Indicating Your Dog Is Infested With Worms

It is worth noting that your dog will not necessarily show all of these symptoms. This is why we recommend regular preventative treatment routine to deal with any infestation before your dog falls ill and spread the worms to other dogs and humans.

The main symptoms of worms in dogs include;

  • Vomiting. If your dog starts to vomit more often, then that can be a sign of worms. Roundworms often cause dogs to vomit.
  • Visible eggs or worms in their feces, fur, or vomit. This is the most apparent sign of worms. Tapeworms often appear in the feces and can be seen moving. However, you may not notice this until the feces have dried. In this case, you will see their eggs look like grains or seed. They also appear in the area near your dog’s rear.
  • Persistent scratching. If you see your dog continually rubbing or scratching their rear area, this is a sign of worms. However, if the scratching continues, you need to speak to your vet.
  • Increased appetite. Intestinal worms and parasites feed on what your dog eats. To compensate for this loss, your dog tends to eat more.
  • Bloated belly or stomach. If you notice your puppies having bloated stomachs, then it could be a sign of tapeworm infestation. Note that puppies can be born with intestinal parasites and worms if the mother had worms while pregnant.
  • Blood in stool or diarrhea. There are many causes of diarrhea, such as poor diet and parasites including tapeworms. Bloody diarrhea can either indicate hookworms or severe disease. If you notice that blood is persisting even after giving your pooch quality dewormers, then it is wise that you contact your vet.
  • Coughing. Hookworms and roundworms can cause dogs to develop a cough.
  • Weight loss or general body weakness. Intestinal parasites and worms eat most of the foods your dog eats. This can cause your dog to shed weight and feel weak over time. However, if these symptoms persist even after administering dewormers, you should talk with your vet.


Common Types of Intestinal Worms in Dogs and How Dogs Get Them

There is no single way upon which dogs get worms and parasites. However, because these intestinal parasites are found in the gastrointestinal tract, they have to pass through the dog’s mouth and digestive tract.



These intestinal parasites are one of the most stubborn and cunning worms. They are of two species- Toxocara Canis and toxascaris leonine. They both absorb nutrients from the gut, and they are white and long in appearance (spaghetti-like). Dogs get infected by roundworms when they ingest something that is contaminated with feces containing roundworm eggs. Once they swallow the eggs, they hatch in their gut, thereby releasing a larva that penetrates the walls of their intestines.

The larvae find its way into the bloodstream where they are transported to the alveoli of the lungs. They crawled up to the airway where they are coughed up and swallowed back. If the dog is pregnant, larvae can reach the placenta and infest unborn puppies. Puppies can also get larvae from dog’s milk.



Dogs can get hookworms in two ways. The first method is through ingesting eggs from something that was contaminated with feces of an infected dog. The second method is quite unique. When eggs in the stool are not ingested by a dog, they hatch larvae after 5 days. These larvae crawl on soil and penetrate dog’s skin in between the paws when a pooch walk on the soil. After it reaches the dermis, it goes into the bloodstream and reaches the lungs, from where they crawl up the airway and are swallowed to the gut. Regardless of the method, they take to get into your dog’s body, hookworms will end up in the colon.

They are generally short and have teeth that help them suck blood. They are aggressive and can lead to loss of weight and cause general body weakness.



These worms have a unique way of getting transmitted as they need an intermediate host. They are spread in the same way other worms are transmitted. When an intermediate host such as a sheep, cattle, pig, or any other host ingest embryo eggs in the feces of an infected dog, the eggs hatch in their intestines. This leads to the formation of larvae, which finds its way to the lung, liver, and other organs. When a dog eats these organ meats in their raw form (that’s without proper cooking and preparation) the larvae are transmitted to dogs, where they mature and hatch eggs.

These worms are longer than other types of intestinal warm, and they live in the small intestines. They rarely harm dogs as healthy dogs can produce enough nutrients to cater for both their body needs and worms. However, very active dogs may experience slight deficiencies in some nutrients.



When an adult whipworm lays eggs in the large intestines, they are pushed to the anus where they are excreted together with the stool of your dog. They are embryonated within 2-4 weeks. The infective larva develops during this period. If a dog licks the soil contaminated with whipworm, these eggs are passed down to a new dog where the larvae are released into the intestines. It grows to become an adult whipworm.


What to Look For In a Dog Dewormer

You can get quality dog dewormers over the counter, but it is essential to ensure you choose the right one for your dog. There is a couple of things you need to look for in a dog dewormer including the type of worm you are treating. If you are unsure which worms have infested your dog or you are using a dewormer as a preventative treatment, then go for a broad spectrum dewormer.

The best broad spectrum dewormer should cover whipworms, hookworms, roundworms, and tapeworms. It is essential to check the number of worms a dewormer treats to know if it suits your dog.

Another critical thing to consider is the type of dewormer your dog needs. Dewormers are available in many forms including chewable tablets, granules, and liquid. All these types are equally effective when used as required. However, if you are administering a dewormer to more than one dog, a liquid dewormer or palatable tablet should not be added to your dog’s food. You need to ensure that each pooch gets the light amount.

The best dog dewormer should determine the dosage of the dewormer by your dog’s weight. Do not under or overdose your dog. Therefore, always choose a dog dewormer that includes dosage and weight guide on its packaging.

It is also crucial to check if the dewormer is suitable for your dog breed and age. The best dog dewormer clearly states the age and breed (small or large) that can be used and whether or not they are safe for lactating and pregnant dogs. If your dog is pregnant and you want to deworm it, choose a treatment that has been tested for pregnant dogs or puppies.

With that in mind, here are the top best dog dewormers on the market;

FAQ About Dog Dewormers


How does a dewormer work?

These are medicine designed to kill intestinal worms and parasites in your dog’s system. These parasites hold on the intestinal wall and are excreted along with undigested food when your dog passes its stool.

The best dewormers kill both the eggs and larvae in your dog’s system. It is essential to follow all the instructions on the packaging and complete the treatment as specified.

How long does it for the dewormer to eliminate worms?

It takes around 2 weeks for a dewormer to eliminate intestinal parasites after the final dose is administered. You can take a stool sample to your vet to ensure all worms have been eliminated. Your vet will check the signs of worms in the stool under a microscope. If your vet notices any signs of worms, he/she will advise on the way forward.


Can one infected dog pass worms to another?

Dog intestinal worms and parasites are transmissible. They are passed on when a dog comes into contact with feces from an infected dog. This can either be through contact with feces or being bitten by a flea that was in contact with infected feces (but this depend on the type of worm).

If you want to prevent the spread of worms, dispose of feces quickly and properly. If your dog gets infected keep them away from other pets to help stop the spread of worms.


Can humans get worms from dogs?

Worms are zoonotic in nature, and this is one of the main reasons you should treat your dog’s worm infestation as fast as possible. That means worms can be transferred from your canine companion to you.

Humans are prone to attack from canine roundworms, tapeworms, and hookworms. However, the least common in humans is the tapeworm. This is because tapeworm’s eggs are transmitted majorly by fleas, and thus human has to swallow a flea to have the same infestation.

Roundworms and hookworms are easily transferable from dogs to humans if you come into contact with dog fecal matter that has overstayed for 5-10 days.

As a precautionary measure, you may need to treat yourself for intestinal worms if you find out that your canine friend is infected too. They may not be able to cope in a human body system, and this makes them more dangerous as they can damage other organs.


Final Thoughts

Intestinal parasitism is one of the significant health problems dogs faces, especially those dogs that spend most of their time outdoors.
