Having dogs infested with worms is not a pleasant experience at all, both for you and your dog. It is dangerous because it easily spreads.

It can spread among your other dogs and even the humans in your home, including yourself.

The infected dog gets hurtful symptoms like vomiting and bleeding in the worst cases. At that point, you need to take the infected dog out of the midst to prevent further spread.

That’s what you are about to learn how to do as you proceed with this article.

Types Of Worms In Dogs

Dr. Jerry Klein, the AKC’s chief veterinary officer, says that if worms in dogs aren’t treated, they can cause serious health problems.

“Worms can be picked up from contaminated soil and your dog’s stool. They can infect other canines, and certain species of worms can also infect humans. That’s why it’s critical to clean up your dog’s feces as soon as possible.”

We’ve compiled a list of some of the most common dog worms that typically harm domestic dogs, along with information on how to contract them and how to recognize them.

They include roundworms, tapeworms, and heartworms. 


Roundworms are among the most frequent intestinal worms seen in dogs. Toxocara canis (T. canis) and Toxascaris leonina are the two forms of roundworms seen in dogs.

T. canis is more common in puppies, but it can also be passed through people. Many puppies are born with roundworms that they picked up from their mother.

As a result, young puppies must receive proper veterinarian care. A feces sample is used to diagnose roundworms and deworming drugs are used to treat them.

If left untreated, roundworms can cause stunted growth and, in severe circumstances, death.

The raccoon roundworm, Baylisascaris procyonis (B. procyonis), is a rare form of roundworm that can infect dogs and is found in some parts of North America. 


Tapeworms are intestinal parasites that dogs get by eating infected fleas or devouring tapeworm or flea-infested wild animals.

The tapeworm egg hatches after the dog eats the flea and attaches to the dog’s digestive lining.

The most prevalent tapeworm identified in dogs in the United States is Dipylidium caninum.

It can be spread from fleas to dogs, providing you with another reason to be vigilant about flea prevention.


Abdominal distension, coughing, a weak pulse, exercise intolerance, weight loss, and, in severe cases, pale gums, hard breathing, and death can all be indications of heartworms.

If your veterinarian diagnoses your dog’s skin issue as a worm infestation, try to isolate your dog from other animals —and people — in your home. This is to prevent him from infecting them.

Symptoms Of Worms In Dogs

It’s not a simple task to detect dog worms, so don’t be discouraged if you make a mistake.

If you are unsure about worms in your dog, or you don’t know what kind they are, your vet will happily check your dog over to see if there’s a problem.

Regular vet visits will allow your veterinarian to detect any potential dog health issues and assist you in resolving them before they become serious.

You should see your veterinarian before trying to come up with a treatment plan on your own, just in case there’s a separate issue at hand.

So you know what to watch for, here are some symptoms of dog worms:

  • Weakness and depression are two of the most common symptoms of depression.
  • Vomiting or diarrhea.
  • A huge weight-producing obstruction of the colon could cause severe vomiting, loss of appetite, and depression (which is usually seen in puppies).
  • A stomach that is unusually enlarged.
  • Despite having a healthy appetite, you’re losing weight.
  • Lungworm can cause coughing and bleeding issues, among other symptoms.
  • Worms are found in dog feces, vomit, or on the dog’s bottom.

Treatment And Prevention Of Worms In Dogs

If your puppy came from a reputable breeder or rescue center, he or she should already be worm-free, since they would have been dewormed before being given to you.

Keep the deworming treatment documentation safe, and ask your veterinarian how to continue the program.

If you maintain track of your pet’s deworming therapy and look for symptoms, the odds of them getting sick from worms are considerably reduced.

Adult dogs, too, require deworming because they may have picked something up on their trips!

Request a dewormer from your veterinarian, as well as further information on worm symptoms in dogs so you can catch them early.

The vet can also inform you how often your dog should be dewormed so that you can establish a regimen.

Ringworm is diagnosed by looking at the infected hairs under a microscope or with a special fluorescent light. They can see ringworm spores using these approaches.

A hair sample may be cultured by your veterinarian for a more precise diagnosis.

Ringworm is self-limiting, meaning it will go away within a few weeks or months on its own.

Not that you shouldn’t take care of it. Treatment shortens the duration of the infestation and aids in its control.

Your veterinarian may recommend a combination of specific shampoos or dips, oral antifungal medicine, or topical treatment, as well as the removal of hair from the affected regions.

Treatment can continue up to six weeks and ends when your dog gets a second ringworm negative culture.

If your dog is suspected of having worms, your veterinarian may request a stool sample.

Because worms in dog feces aren’t always visible to the naked eye, the vet can examine it under a microscope for worm eggs.

Certain worming techniques are required if your dog is traveling with you overseas via the PETS scheme, so check before you go!

Inquire with your veterinarian about these protocols well before any vacation plans, so you’re prepared.

Treating The Environment

Ringworm spores can survive for months in the environment of your pet.

That means many of your dog’s belongings, such as his food and water bowls, toys, and brushes, must be disinfected or discarded.

All pet bedding should be washed in hot water with bleach in the washing machine, or the old bedding should be discarded and replaced.

If the treatment won’t harm the objects, you can destroy spores on carpets or furniture with a solution of 1pint of bleach to 1gallon of water.

Do I Need To Isolate My Dog With Worms?

Some dogs may be unwell and contagious, displaying no signs.

Depending on the disease, the incubation period (the time between exposure and onset of symptoms) varies.

Canine parvovirus, for example, has a five-to-eleven-day incubation time, but rabies can take months or even years.

Distemper-free dogs can infect other dogs for up to 90 days after they’ve recovered. However, most dogs infected with an infectious disease become ill within two to three weeks of being exposed.

If you’re not sure about your new dog’s health—perhaps he was found as a stray—keep him in quarantine for at least two weeks.

To limit the chance of exposure to your other pets, wait a month. If the dog remains healthy, he can be introduced to your home and other pets securely.

How To Quarantine My Dog With Worms

You’ll want to keep the new puppy in a “safe room” until you’re ready to introduce him to the rest of the family.

Choose a spot that is easy to clean, such as the laundry room or a covered porch. Try to keep the quarantine space well ventilated.

Determine that the newcomer has all the canine accessories, such as food and water dishes, toys, and a bed.

There should be no direct contact between the new dog and your existing dogs, including sniffing through the screen or beneath the door, as even this poses a risk of disease transfer.

To keep the quarantine space and canine requirements clean, use a disinfectant. Bleach diluted one cup bleach to two gallons of water is an effective all-purpose disinfectant.

Remember to disinfect yourself after interacting with the new dog, especially after cleaning up any puddles or mounds that may have occurred.

Sick dogs frequently lose control of their elimination and should not be expected to follow house training until they have recovered.

When interacting with the isolated infant, wear an oversized shirt and sweatpants or another “puppy-only” clothing like a smock or apron.

Before making touch with the other pets, remove the special smocks and properly clean your hands.

Don’t forget to wipe the bottoms of your shoes to avoid bringing anything nastier out with you.

Fill a shallow basin with a tiny bit of disinfectant, and after you leave, walk into the liquid with your shoes to kill any germs that might infect your other pets.

Overall, worms in dogs are normally not a cause for concern — as long as they are caught and treated promptly, your dog will be as happy as ever!

Other parasites to be on the lookout for include mites and ticks.
