Process of Deworming

The first thing to do is to identify the type of worm or worms that have made your dog’s body their home. Usually, a stool test will help determine this.

A vet will look at your dog’s stool sample for live worms or worm eggs. In case they suspect an infestation of heartworms, a blood test might be done.

Once the vet figures out which type of worms are in your dog’s poop, they will either prescribe an oral medication or a deworming shot.

What to Expect After Deworming?

After taking the medication, as soon as your dog poops, you will be able to observe pieces of or whole dead worms in their stool. Your puppy may also have diarrhea that can last for up to 3 days. This shouldn’t be a cause for worry as it is fairly common.

Also, for the first few days after deworming, your dog might experience a lack of appetite and be a little lethargic. If these effects last for longer than 2 weeks, you should see a vet.

Signs that Deworming Hasn’t Worked

If you can still see worms in dog poop after deworming has been over for many weeks, it is probable that the treatment did not work. In severe cases, your dog might even throw up worms.

If your puppy still has worms after deworming, you should consider giving them another dose of the deworming medication.

What Are the Benefits of Deworming a Dog?

Deworming is important to get rid of worms from your dog’s body. While your adult dog must be dewormed once every six months, in the case of young pups, the recommended deworming schedule is at 2, 4, 6, 8, 12, and 16 weeks of age. This process has the following benefits:

Reduces Health Problems

Worms affect your dog’s appetite and fitness. In minor cases, your dog will suffer from weight loss as a result. Additionally, other health issues can also occur, depending on the type of worm your dog carries. Roundworms cause colic (stomach pain) while hookworms can cause coughing and diarrhea.

With regular deworming, your dog will not suffer from such health problems.

Prevents Transmission of Parasites to Humans

If your pup or dog has a worm infestation, their poop will have worm eggs. These can get ingested by children and also get transmitted via the coat of the dog when it sits or lies on any surface. In turn, they can cause diarrhea and other health issues in kids as well [1].

When you deworm your puppy, you make sure that it does not transfer disease-causing parasites to attack the other members of your family.

What Are the Side Effects of Deworming?

While deworming your dog is an essential part of its healthcare, the process does carry a risk of some side effects. Here are the most common ones:


When administering deworming medication to your pup, it is fair to expect diarrhea as a consequence. A small degree of it serves the important purpose of flushing parasites out of their body. Pooping out worms after deworming can last for a few days. But if it doesn’t stop beyond that time, you should consult your vet regarding a solution.

Bloody Poop

If while observing your dog’s poop you notice red-colored streaks in it, it is a sign of blood-mixed stool. This is quite normal, especially if the amount of blood is not a lot, and goes away on its own in a day or two.

However, if your dog continues to poop bloody feces for longer than that, you should visit a vet as soon as possible.

Mood Swings

Due to diarrhea and other symptoms after taking a deworming medication, your puppy might seem disinterested or lethargic in general. You will notice this more if it isn’t as excited about food anymore. At times, it may also become irritable and experience changes in its mood.

As pet owners, you should know that this is temporary, and as soon as the treatment wears off and the worms are all dead or flushed out, your pup will return to its usual bouncy and chirpy self.

How to Keep Your Puppy Healthy After Being Dewormed?

You can help make the deworming process go easier for your dog by following these simple tips:

  • Allow it to rest for as long as required.
  • Give it a comfortable dog bed to lie in.
  • Stick to a healthy diet plan for your dog which includes nutritious food as well as plenty of water.
  • To make sure that your puppy does not get worms again, place trash cans out of their reach. Also, keep the surroundings clean to prevent flies and other insects.
  • Keep any animal carcasses far away from your dog’s reach and also far away from your property as they draw in fleas, houseflies, and parasites.
  • Fleas are an intermediate host of tapeworms. To get rid of them, apply an anti-flea medication to your pet’s body regularly.
  • Give a monthly heartworm treatment to your dog in order to prevent these dangerous parasites from growing inside their body.
  • Thoroughly wash your hands after you pick up their waste or clear out dog poop so that you don’t transfer worms to yourself, family members, or other pets in the house.
  • Make regular visits to the vet and get your dog checked for worm infestations and the progress of the deworming treatment.
