How Long Will My Puppy Poop Worms After Deworming? What You Need To Know

When it comes to caring for your dog, you will need to make sure that they visit the vet regularly to ensure they go through the proper procedures for excellent health and happiness. One of the essentials you need to take care of is deworming. Once you deworm your puppy, they will be safer! But one of the after effects of deworming can be pooping out worms. You might end up wondering how long your puppy will poop worms after deworming. To help you out, I will explain what you need to know about deworming and how to prepare to care for your puppy after the procedure.

What is deworming?

Just like the name states, deworming is getting rid of parasites from your dog’s stomach. Unfortunately, your dogs are one of the ideal hosts for worms, as they tend to explore and taste anything they see around them, from trash to poop! Because of that, the worms can spread to fellow animals or into your dog’s system, affecting your poor pup’s digestion!

Parasites and worms will end up giving your dog diarrhoea or nausea, similar to humans who suffer from bacteria in their digestive systems. Through deworming your dog, the medicine will get rid of all the parasites from his body, making him feel better again.

Worms are inevitable and will be part of your puppy’s life. After all, they are born with them! That is why regular deworming is important. Ideally, deworming sessions occur every two to four weeks of a puppy’s life until he reaches four months old.

There are a few ways to deworm your dogs. When you go to a vet, he may either give him oral medicine or an injection to kill the parasites in his body. While it is possible to deworm puppies yourself with worming treatment, it is recommended that you consult your dog’s veterinarian first.

Deworming your dog

Deworming your dog is crucial, as this not only gets rid of the parasites from his body, but it also prevents him from spreading them to other dogs and humans! Through deworming your dog, you can keep him healthy and free from worms, which may end up being fatal. Because of this, it is crucial to deworm your dog every few months, especially if he suffers from the symptoms such as diarrhea or nausea.

A stool test can diagnose your pet to see if he has worms. It is best to consult your vet regarding this, rather than self-diagnosing the condition. As a professional, they will be able to determine what type of worm your dog has and which medication he should take to get rid of it. You can prevent worms from worsening by taking your dog to a vet for regular deworming and checkups, especially if he has abnormal bowel movements or a moodier attitude.

How long will my puppy poop worms after deworming?

When deworming your dog, there are a few things to expect. As previously mentioned, your dog will poop out worms because of the medicine you gave him to get rid of the parasites. While some medications make the worms dissolve, others end up paralyzing the worms. Once paralyzed, they detach from your puppy and pass through the intestinal system into his stool or vomit. He may begin pooping worms as early as an hour or two after deworming, but it more commonly begins 12 hours after deworming and lasts for about two weeks.

Other things to expect after deworming include your dog vomiting or suffering from lack of appetite and an upset stomach. Your dog might also have less energy, a bloated stomach, or regularly scoot its butt along the floor as a way to get rid of the worms. You should consult a veterinarian if your dog experiences these symptoms for over two weeks, as these side effects may be fatal.

Tips to keep my puppy healthy after deworming

Since your puppy may feel discomfort throughout the whole deworming process, here are some tips to keep him as comfortable as possible:

    • Keep your puppy well-rested in a comfortable dog bed. While you will want him to have proper exercise, it is crucial for him to rest and pass the worms before he builds the strength to go and play again.
    • Give your dog a healthy meal plan with an adequate amount of vitamins and protein. Since he may have diarrhoea, keep him well-hydrated and make sure he has water nearby. If you have trouble finding healthy food for your dog, Taste of the Wild – Canine Formula might be a good choice.

    Thank you for the information. We are first time dog owners and our newest little addition has worms. Our daughter has been very worried about him, wondering why he’s been so sleepy. One, we knew it was because he was sleepy but, she thought it was serious. This article brought so much comfort, understanding, and useful information.

    This article probably gave me more information than all the 10 sites i looked at previously. i have been feeling like the 2 week wait for the second dose seems like a very long time, because I am still seeing worms in my “just shelter adopted, blind, 13 yr old, 13 lb little dog”, but your information gives me comfort. And I agree with Junae, I can’t wait for this process to be over.

    Hi I had a few more questions about this process. I took my 8 week old puppy for her first deworming. Right when we got home she had diarrhea and I believe I saw a worm (size of a grain of rice) she had diarrhea that whole day so we took her to the vet since we didn’t know if that was normal. The vet gave the Parvo Test which came back negative and just prescribed antibiotics and that was it. He said he couldn’t diagnose what is wrong with her but said he’s hopeful with the medication she’ll be fine and to come back in two weeks. Since then she’s continued having diarrhea with white dots in it. At first it smelled horrible (like parvo) but now it hardly smells and is mucusy. This morning, Friday, she didn’t poop all night so when she did it was very mucusy and had a whole mountain of white dots that sat on top diarrhea. I don’t get what’s going on we put her on a bland diet of chicken and rice so I wasn’t sure if the dots are just digested rice grains or eggs from the worms. She’s also scooting her but along the floor very often. Any tips or opinions to what this may be would help!

    I did not see any worms in the bowel movements. Does that mean she has none?

    My son and daughter-in-law just got a new puppy. She has been de-wormed by the previous owner. She is pooping worms and occasionally dropping worms on their clothing (which are alive). My granddaughter, who is one year old, ate puppy poo before they could grab her. Is she in serious health danger??? Also my daughter-in-law is pregnant. Is there any risk to her or the unborn baby?

    Thank you! Really nice article. Put my mind at peace. Just have one question maybe you can help. My vet says the deworming process only happens 3 monthly is this right?
    Feel so sorry for my puppy.
