Common but serious.

Roundworms/ascarids (Toxocara canis, Toxascaris leonina) are the most common parasitic worm that infects dogs.¹ They live in dogs’ digestive systems, causing discomfort, illness and even death in severe cases.

How dogs get roundworms.

Many puppies are born with roundworms or contract them from their mother’s milk. In addition, dogs often pick up roundworms by eating things they shouldn’t, like contaminated soil, wild animal remains and feces.

Signs of a roundworm infection.

Dogs don’t always show signs of roundworms, but infected dogs may exhibit:

  • Vomiting and/or diarrhea
  • Weight loss
  • Bloated stomach
  • Dull coat

You may also see a few of the long, white worms in your dog’s feces or vomit.

IMPORTANT INFORMATION: Dogs should be tested for heartworms prior to use. In a small percentage of treated dogs, digestive and neurological side effects may occur. Please see full product insert for more information.
