Dogs usually get tapeworms by accidentally eating something that’s carrying tapeworm larvae, most often an infected flea.

Quick Scoop

  • The most common way dogs get tapeworms is by swallowing an infected flea while grooming or chewing at itchy skin.
  • Inside that flea are immature tapeworms; once swallowed, they are released in the intestine, attach to the gut wall, and grow into adult worms.
  • Dogs can also get certain tapeworms by eating infected wildlife like rodents or rabbits, especially if they like to hunt or scavenge.

Main Ways Dogs Get Tapeworms

  • Flea route (most common):
    • Flea larvae eat tapeworm eggs in the environment.
* Those larvae grow into adult fleas still carrying tapeworm larvae.

* Your dog bites, chews, or grooms and accidentally swallows one of these fleas.
  • Eating infected prey (other tapeworm species):
    • Some tapeworms use small mammals like rabbits and rodents as “intermediate hosts.”
* When a dog eats an infected rabbit or rodent, the larvae in that animal’s tissues develop into adult tapeworms in the dog’s intestines.

What This Means For You

  • Good flea control (on the dog and in the home/yard) is one of the most important ways to prevent tapeworms.
  • Limiting hunting or scavenging, and not feeding raw, wild game helps reduce risk from prey-borne tapeworms.
  • If you ever see rice-like segments near your dog’s anus or in their stool, that’s a common sign of tapeworms and a reason to call the vet for deworming and flea-check advice.
