Deworming is critical for removing internal parasites from young pups and new dogs brought into a home. Parasites are a serious threat to a dog’s health. In addition, certain forms of parasites can be passed on to human family members.
All puppies should be dewormed every 2 to 4 weeks until they reach the age of 12 weeks. They should subsequently undergo parasite elimination and prevention treatments once a month until they are 6 months old. After 6 months, an adult dog should be treated every 1 to 6 months, or as recommended by your veterinarian.
While there is no denying that deworming is vital, there are numerous questions concerning this technique. Many pet parents, in particular, are concerned about whether or not dewormers induce diarrhea in dogs. So let’s see if we can figure things out.

Here's what we'll cover:
Side effects of deworming puppies
The primary classes of anti-parasite medications (avermectins/benzimadizoles, for example) are quite safe. Having said that, always follow your veterinarian’s deworming advice.
Puppies with a high parasite burden (number of parasites) may feel sick after the therapy. For example, if all of the parasites in the intestines died simultaneously, the lining of the intestines would become irritated, resulting in diarrhea, vomiting, and a loss of appetite. However, this is usually a self-limiting condition, and puppies return to normalcy within two days.
Higher doses of heartworm preventive (ivermectin) are particularly efficient against most parasites; however, some breeds cannot tolerate the higher dose. This is due to a mutation in the MDR-1 gene, which codes for proteins that protect the brain (blood-brain barrier). When dogs with the MDR-1 mutation are given medications such as ivermectin, opiates (morphine-like painkillers), and chemotherapy, they can experience severe side effects. The list might include fainting, tremors, and even death.
Diarrhea: common side effect of deworming
Intestinal worms are the most prevalent type of worm in puppies. They attach to the intestine and absorb nutrients from food as it passes through. When the treatment is administered and the worms die, they fill up the gut, prompting the body to flush them out with the extra liquid.
As a result, diarrhea is one of the most prevalent side effects of deworming young dogs. To get rid of the dead worms, his body will excrete many feces.
So, if the infestation is severe, expect to see them in his poop or even on their own in enormous bundles of what looks like spaghetti. Sorry for the food analogy, but it’s all part of the puppy course (or, hopefully, not!)
It is typical for your dog or puppy to poop a lot after being dewormed. According to Vet Info, diarrhea is a probable adverse effect of deworming a dog. However, it is pretty uncommon for a dog to attempt to spit out a dewormer tablet or to vomit afterward. Because tablets might be difficult for puppies to swallow, certain medications are offered in liquid form.
Nausea, vomiting, lack of appetite, and diarrhea are possible side effects of drugs such as pyrantel pamoate, which treat hookworms, roundworms, etc. Giving the dose alongside food can assist with nausea and gastrointestinal troubles. However, these effects are usually transient. And the benefits of deworming surpass all of the treatment’s drawbacks (diarrhea included).
