Deworming is an important aspect of dog care that helps keep them healthy and happy.

But when it comes to regularly worming your dog, you might wonder whether deworming dog before or after meal is better.

In this article, we will provide you with the knowledge you need to make the best decision for your furry friend.

Is Deworming Dog Before Or After Meal Better?

When should I deworm my dog? 

Before the meal is better. Generally, you should wait at least 60 minutes after deworming your pet to give them food, even though it can take them several hours to completely absorb the medication.

Doing so when they are hungry also promotes them to devour that medicine better. And the treatment for puppies will lessen the medication’s efficacy if you give your dog too soon after administering it.

Moreover, since pesticides might make your pet’s skin more fragile, you should wait a couple of hours after deworming puppy to take your pet outside to prevent any negative responses to outdoor allergens.

Providing your pet with lots of fresh water after the deworming medication is crucial because the drug might dehydrate them.

What Are The Worm Infestation’s Symptoms In Dogs?

Worms may result in major issues for dogs, so it’s crucial to pay close attention to any changes in behavior or health. 

The symptoms of worms in dogs can vary with different worm types and the infestation’s severity. However, some common signs include the following:


Dogs’ most typical symptoms of roundworms are diarrhea, vomiting, dullness, bad coat condition, loss of appetite, and worms in the feces.

Also, bloating and anemia are some other the states that puppies may encounter.

Additionally, chow pitbull lab mixe, corgis, border collie mixes or other dogs with roundworms may exhibit a cough, as the worms can migrate to the lungs. Occasionally, roundworms can also be seen in the dog’s feces or vomit.


Hookworms are among the most popular intestinal worms in puppies. Some signs of hookworm infestation in puppies are:

  • Diarrhea: Hookworms can cause severe diarrhea, which may contain blood.
  • Anemia: Hookworms feed on blood and can have anemia, which can be life-threatening in puppies.
  • Weight loss: The parasite results in weight loss in puppies as they steal nutrients from their food.
  • Weakness and lethargy: Puppies with hookworms may become weak and lethargic due to anemia and malnutrition.
  • Poor coat condition: Hookworms can create poor coat conditions in dogs because of poor nutrition intake.


Owing to irritation in the anal region, dogs with this type of worm might be scratching all over the floor. Dogs with whipworms may experience abdominal pain, which can render them restless or uncomfortable.

Moreover, they may experience slow development, diarrhea with mucus, weight loss, lack of appetite, gastrointestinal discomfort, and a shaggy coat that is poorly shaved.


Tapeworms in puppies manifest themselves via various indicators, namely vomiting, weight loss, and abdominal discomfort. However, many adult dogs with tapeworms show no signs at all.

One of the most recognizable signs of these types of worms in dogs is the presence of tapeworm segments, which can often be seen in a dog’s stool or around the anus.

These segments resemble small grains of rice and can signify that the dog is shedding worm eggs.

It’s important to note that dogs can contract tapeworms by ingesting fleas, so keeping your dog free of fleas is important in preventing tapeworm infestations.

What Are The Most Common Mistakes When Deworming Dogs?

When it comes to deworming dogs, there are several mistakes that pet owners can make. They could reduce the effectiveness of the deworming treatment or even harm the dog.

Some of the most common mistakes when deworming dogs include the following:

Not Completing The Full Course Of Treatment

Often, oral antiparasitic medications are used to deworm patients.

Nevertheless, it is also sometimes overlooked that the second dosage must be administered 15 days following the first for deworming to be successful.

Giving Medication Without A Vet’s Guidance

The most frequent misconception is this one. We learned that our dogs must be dewormed, but instead of taking the pet to the doctor first, we bought an antiparasitic treatment. 

However, different deworming treatments target different types of worms, and using the wrong medication can be ineffective or even harmful.

It’s crucial to remember that the vet will examine your pet’s physical health, weight, and lifestyle during the session, as well as whether or not he lives with youngsters, among other things.

They can choose the correct dose for your dog based on this information.

Dewormed One Pet Only When You Have Many Animals

Numerous pet owners often deworm one but not all of their animals at once. 

This bad habit leads to incomplete and inefficient deworming, which puts your pet’s health at risk because any remaining worms will still be a source of infection.

Using An Oral Antiparasitic Without Ensuring That It Has Been Adequately Ingested Or Absorbed

Giving our dogs antiparasitic medicine in an attempt to deworm them frequently results in the dog returning, spitting, or throwing up after a while.

This occurs since many oral antiparasitic drugs have extremely harsh tastes or are flavored with ingredients that dogs may not appreciate.

It is advisable to pick an antiparasitic drug for your pet that doesn’t involve ingestion, such as topical and internal action, to avoid this rejection.

It’s important to work closely with a veterinarian to determine the appropriate deworming treatment for your dog and to ensure that it is administered correctly.


How Long Does Dewormer Last In Dogs?

The duration of effectiveness of a dewormer in dogs can vary depending on the type of dewormer and the type of worm being targeted.

Most dewormers typically remain active in the dog’s system for 24-48 hours and then are excreted in the feces.

Some dewormers require a second dose to be given 2-3 weeks after the initial dose to eliminate all parasites.

You should comply with the product instructions or those provided by a veterinarian for a safe dose.

How Long Does It Take A Dewormer To Work On Dogs?

How quickly does dewormer work in dogs? Most deworming medications continue to act for two to six hours after being taken. A few drugs will kill the worms, while others will immobilize them.


Be it deworming dog before or after meal, the most important thing is to follow the instructions provided by your veterinarian, though doing this before feeding your dog will yield better outcome.

Remember that deworming is an important part of dog care and should be done regularly to ensure your puppy lives happily.
