Intestinal worms in cats and dogs  


Intestinal worms represent a persistent threat to our precious four-legged companions. They infiltrate their bodies and are sometimes transmitted to their young during lactation and gestation. 

It's important to know that almost 30% of our furry friends can be affected by intestinal parasites, which the naked eye cannot see. However, they can be detected by analysis. The transmission of these parasites occurs primarily through their eggs, which can be passed on to other animals and even humans who meet the infected pet. 

With the right preventive measures and in-depth knowledge of these parasites, Medzy | Pharmacie Sonia Boutin Inc. is committed to helping you preserve your pets' health. 

Types of intestinal worms

The most common intestinal parasites in dogs and cats are roundworms, tapeworms, whipworms and hookworms. 


Roundworms are parasites that can infect the intestines of cats and dogs when they ingest eggs in a contaminated environment. In Canada, these worms are among the most common parasites to affect humans. While healthy individuals can typically clear the infection with their immune system, children and those who are frail may be more susceptible to complications. 


Two flatworms, Dipylidium caninum and Taenia, can parasitize cats and dogs. Animals can contract flatworms by ingesting infected fleas or prey, such as rodents harbouring larvae.  


Whipworms are intestinal parasites that can infect dogs. Dogs can contract whipworms by ingesting eggs present in the contaminated environment.   


Hookworms attach themselves to the intestinal walls and feed on the animal's blood, sometimes causing anemia in infected animals. The parasites are contracted through soil contaminated with larvae and are more common in dogs than cats. 


Your cat or dog's infestation with intestinal worms goes unnoticed at first. Once the infestation has gained ground, several symptoms may appear:

  • Presence of blood or worms in stools  

  • Diarrhea  

  • Vomiting  

  • Dull hair  

  • Weight loss  

  • Anemia  

  • Lung problems 

How can I prevent intestinal worms?  

Annual fecal tests by a veterinarian are necessary for adult cats and dogs to detect infections. If the tests return positive, the vet will adjust the treatment based on the parasite type. Depending on your pet's age and lifestyle, your vet will determine the best frequency for effective treatment. 

For young animals, starting deworming treatments very early is essential to avoid health problems that could hinder their growth.
