Roundworms in Dogs: How to Diagnose and Treat

Roundworms or ascarids are a type of parasite found inside the intestine of animals and live on the food obtained there. These worms are mostly white or light brown in color and grow up to a few inches. If your dog has roundworms in his intestine, there are chances of seeing them in your dog’s stool and vomit.


At times dogs don’t show any sign of infection, but mostly they do. Being a dog parent it is your responsibility to see if it is suffering from pot-belly, weakness, vomiting, diarrhea, belly pain, weight loss, dull coat or weight loss. However, it is also very important to observe its poop or vomit regularly. In case you see any of these signs in your dog, take your dog to the vet. He’ll test a sample of your dog’s poop and if required, he will ask you to start a set of treatments.


Fortunately, plenty of safe and effective dog wormers are available in the market which can kill and stop the growth of worms effectively. Mostly, vets prescribe the dogs one to three doses at first, which kills the adult worms. As this is very common in puppies, many veterinarians deworm puppies when they are just 2-3 weeks old, just to be safe.

Even after the treatment of your dog, he should be taken to vet for regular fecal exams. Pups should be taken 2-4 times a year whereas the dogs older than 1 year and more should be taken to the vets at least twice a year.

How dogs get roundworms

Mostly puppies get them and fall sick. They might get these worms from:

  • Mother: If the mother of your puppy is infected with roundworms, she might just pass them to the puppy before his birth. He may also get them by drinking her milk.
  • Surrounding: Your puppy may eat roundworm eggs from other animal’s poop. He may also get infected if he eats mice or other infected small animals.
