Roundworms in Cats & Dogs

Did you know that roundworms like our pets so much, they are a common intestinal parasite found in cats and dogs? With eggs shed through the stool of already infected animals and left behind in the environment, your pet can easily become infected through everyday activities.

Luckily you can treat your cat or dog at home with effective dewormers. Continue to help reduce the risk of these parasites by keeping pet areas clean, regularly removing pet waste in your yard or litter box and controlling rodents.

Round Worm

How do cats and dogs get roundworms?

  • Kittens and puppies are typically infected with roundworms at an early age, commonly through their mother
  • Pets may ingest roundworm eggs (sometimes lying dormant for years) through sniffing or eating infected dirt, plants, or stool
  • Pets may eat other animals already infected with roundworms, such as rodents, earthworms and birds

What are the symptoms of roundworms?

Not all pets show symptoms. For those that do, you may notice:

  • Coughing
  • Diarrhea
  • Potbelly appearance
  • Visible roundworms in stool or vomit
  • Vomiting
  • Weakness
  • Weight loss/malnourishment

What do roundworms look like?

Roundworms are tubular and can remind you of cooked spaghetti: pale in appearance — white or light brown — and with smooth, non-segmented bodies. Growing up to several inches long, they can be seen by the naked eye. Look for them in your cat’s or dog’s stool.

Can humans get roundworms from pets?

Yes. We can accidentally ingest roundworm eggs after animals – including our own pet – shed them in our environment. For example, forgetting to wash hands after gardening, or children playing in contaminated dirt and grass.
