Tapeworm under microscope (caption: Tapeworms In Dogs)You’ve probably seen at least one cringe-worthy video of an unbelievably long tapeworm being pulled out of an animal or even a human. Yes, tapeworms are disgusting, but unfortunately, they’re also easily transmitted to our pets.

How do you know if your dog has them? And are tapeworms a serious health threat? We answer all of your questions about symptoms, treatment, prevention and more.

Article Overview

What Are Tapeworms?

Tapeworms are flat, segmented intestinal parasites that live in dogs, cats and many other animals. They use their hook-like mouth to attach to the wall of the small intestine, where they absorb nutrients from the dog. There are several types of tapeworms, but the most common in dogs is Dipylidium caninum. Adult tapeworms in dogs can reach anywhere from 4 to 28 inches in length.

How Do Dogs Get Tapeworms?

Rather, the tapeworm has to have an intermediate host to become infectious in dogs. Dipylidium caninum uses fleas as its intermediate host, but other species of tapeworms use other animals, like rodents, as their host.

Here’s the cycle of infection:

  1. A dog ingests a flea or rodent, bird, rabbit, etc., that’s harboring tapeworm eggs. Dogs can easily ingest fleas when they’re grooming themselves or another dog or cat.
  2. The eggs settle into your dog’s small intestine and develop into an adult tapeworm.
  3. As the adult matures, individual segments called proglottids break off and are passed in the feces. Since each segment contains tapeworm eggs, the cycle of infestation can easily continue.

It can take about 3 weeks from the time your dog swallows a flea or ingests another infected animal to the time tapeworm segments appear on his rear end or poop.

Symptoms

The most obvious sign that your dog has tapeworms is that he’s scooting his butt along the ground or rug and/or licking his anal area a lot. Tapeworm segments can stick to the fur around the anus, and this causes irritation. You may also notice these segments around his anus or on the surface of his poop — they resemble small grains of rice (and some may still be moving).

TIP: Another major reason dogs scoot their butts along the ground is when they have impacted anal glands, so be sure to rule out this condition.

Tapeworms in puppies can be more serious (especially if they’re very young) and can cause a lack of normal growth, intestinal blockages and anemia.

Diagnosis & Treatment

Bottle of Drontal PlusYour vet will make a diagnosis after either seeing segments on your dog’s anus or in a stool sample. Occasionally your vet may need more than one sample because tapeworm segments and eggs aren’t always passed every time your dog poops.

Your vet will give your dog a one-time injection or prescribe an oral dewormer, both containing praziquantel, which causes the tapeworm to dissolve in the small intestine. Praziquantel is safe and usually has no adverse side effects.

Can People Get Tapeworms?

The risk of getting the Dipylidium species from your dog is minimal because you’d have to swallow an infected flea. In rare cases, this happens with small children, but this infection isn’t very serious.

Humans can get other types of tapeworms not associated with our dogs. This can occur when you consume undercooked meat from an infected animal (beef, pork and fish are the main carriers). It’s also possible to get tapeworms in unsanitary conditions, e.g., in underdeveloped areas of the world where sewage isn’t well contained.

Personal Experience

Michelle, Co-Founder of Canine Journal, shares her own experience with tapeworm.

When traveling in Central America, my husband and I were infected with tapeworm and giardia. The symptoms were horrific and we would not have recovered well without a doctor. I would urge pet parents to take their dog in for an exam the minute they suspect either concern since both require medical attention, in my experience.
