Side effects of worming dogs

Written by meadow milano | 13/05/2017

Side effects of worming dogs can mimic the infestation itself. Parasites are common in the new puppy, and therefore the vet will take a stool sample to determine the presence of ova and parasites during the dog's first checkup.

Side Effect of Vomiting

Canine dewormers can be very harsh on the gastrointestinal system, causing nausea and vomiting. If this occurs, the dog needs to have access to fresh water at all times to prevent dehydration.

Side Effect of Diarrhea

Diarrhoea can be a troubling because it can cause rapid dehydration. Persistent diarrhoea or blood in the stools should be reported to the vet immediately. Offering sips of water to the dog can help stave off dehydration.

Side Effect of Lethargy

When the dog is noticed to be listless and not playful, a trip to the vet or emergency animal hospital is imperative. The condition of the dog can rapidly deteriorate if immediate treatment is not instituted.

Side Effect of Seizures

Seizures can be a dangerous and life-threatening. Some anti-worm medication are neurotoxic and can cause the dog to seize and become unresponsive.


Most dogs that receive anti-parasitic medication will not experience side effects, but if they do, treatment needs to be employed. Treatment for severe cases can include administration of IV fluids to replace lost fluids from diarrhoea and vomiting. If side effects are mild, treatment is geared toward symptomatic relief such as replacing fluids orally and a diet of rice and chicken as approved by the vet to halt diarrhoea and prevent dehydration.
