Seeing little white worms in your dog’s poop can be alarming, but it’s important to know that intestinal worms are common in canines. Some dogs may not show any signs if they have a small worm load, while heavy loads can make them more obviously sick or even be fatal. Regular fecal examinations by your veterinarian can help ensure that your dog remains as free from worms as possible!
What Are Worms?
Worms, also known as intestinal worms or parasites, are common in dogs. The most frequently diagnosed intestinal worms in canines include roundworms (ascarids), hookworms, whipworms, and tapeworms. Worms acquire their nutrition from their host, in this case, a dog. They absorb the nutrients meant to keep the dog healthy. They can cause various health issues, and the dog’s age, size, and overall health and the type and number of worms can mitigate or exacerbate the damage. While you may be familiar with worms living in the stomach and intestines, they can also be found in other organs if they migrate, such as the heart, lungs, and kidneys.
What Are the Common Types of Intestinal Worms That Dogs Can Have?
- Roundworms: Also known as ascarids, these are common in dogs, especially puppies. In dog poop, they look like long strands of cooked spaghetti. The larvae of the species Toxocara canis can also infest and migrate through tissues and organs in people.
- Hookworms: There are several species of hookworms found throughout the world. These small, thin worms have a hooked-shaped mouth part on one end.
- Whipworms: Adult worms of this species are usually found in the colon and cecum. They are small, look like a piece of thread, and are larger at one end than the other.
- Tapeworms: These are also known as cestodes, and the adult worms are segmented and are found in the small intestine. Tapeworms may appear as small segments of rice in dog poop or surrounding the anus.

How Are Intestinal Worms Diagnosed in Dogs?
Most cases are diagnosed by the owner collecting a poop sample from their dog and taking it to a veterinarian. The vet may perform a fecal flotation test, which is where the feces is placed in a solution to prepare it for examination under a microscope to detect any parasite eggs. Adult worms or segments can also be collected and taken to the veterinarian for identification. Keep in mind, however, that worm eggs may not always show up on a fecal test.
How Are Intestinal Worms Treated in Dogs?
Most intestinal worms can be treated with an antiparasitic drug. Dewormers are available in many forms, including oral liquid medication, tablets, injections, or topical applications. Pyrantel pamoate (Strongid T) is one type of oral antiparasitic treatment. Certain monthly heartworm preventatives can also concurrently treat roundworms, hookworms, and whipworms. Pyrantel pamoate, however, is ineffective for tapeworms. These cases may need to be treated with praziquantel.
- Fenbendazole
- Milbemycin
- Moxidectin
Treatments may need to be given for a few weeks at a time, depending on the dog’s age and diagnosis. If you notice worms in your dog’s poop or vomit after giving them a dewormer, it means the treatment is working.
How Can You Prevent Worms in Your Dog?
- Have your dog’s poop tested every 6–12 months for microscopic worm eggs.
- Treat your dog with a monthly heartworm preventative that also treats intestinal parasites.
- Keep your dog’s environment clean and dry.
- House kenneled dogs on concrete rather than dirt.
- Keep your dog up to date on flea prevention.
- Ensure that your female dog is free of parasites prior to breeding and kept out of contaminated areas to prevent re-infestation.
- Treat puppies 2 weeks after birth and at repeated intervals of 2–3 weeks until they are 2 months old, then treat them once a month until they’re 6 months old.
- Talk with your veterinarian about the most appropriate deworming program for your dog and/or puppy.
