One of the most common worms found in dogs is a tapeworm. Tapeworms are an intestinal parasite, meaning that they’re inside of your dog’s intestines. Along with roundworm, hookworm, and whipworm, this flat, segmented worm is found in dogs, cats, humans, and many other species around the world. Here’s what you should know about tapeworms in dogs, including symptoms, diagnosis, and subsequent treatment.
Hey there fellow dog lovers! Today we’re diving into something that might make your skin crawl a bit but it’s super important for keeping your furry friend healthy. Yep, we’re talking about tapeworms – those unwelcome intestinal guests that can make a home in your dog’s digestive system.
I’ve spent countless hours researching this topic (and yes, looking at some pretty gross images) to bring you the most accurate info about how these parasites get transmitted to our canine companions. Trust me, understanding this cycle is key to preventing these unwanted hitchhikers!
What Exactly Are Tapeworms?
Before we jump into transmission let’s get to know what we’re dealing with
Tapeworms are flat, segmented intestinal parasites that belong to the cestode family, which is different from other common intestinal worms like hookworms and roundworms. The most common tapeworm species found in dogs is Dipylidium caninum.
These parasites are pretty distinctive looking:
- They’re flat and segmented (like a tape, hence the name)
- Adult tapeworms can grow up to 11 inches (30 cm) long
- They use hook-like mouthparts to attach to your dog’s intestinal wall
- The segments (called proglottids) look like grains of rice or cucumber seeds
- Each segment can contain up to 20 tapeworm eggs
The Surprising Truth About Tapeworm Transmission
Here’s where things get interesting! Unlike many other parasites, dogs DON’T get tapeworms directly from eating feces of infected animals. The transmission cycle is actually more complex and requires an intermediate host.
The Primary Transmission Route: Fleas
The most common way dogs get tapeworms is through fleas. Yep, those tiny jumping pests aren’t just annoying – they’re tapeworm taxis! Here’s how it happens:
- A tapeworm egg gets released into the environment when a proglottid (segment) dries out
- A flea larva (baby flea) ingests the tapeworm egg
- The tapeworm egg develops inside the flea as it grows into an adult
- Your dog either:
- Accidentally swallows the flea while grooming
- Bites at a flea bite and swallows the flea
- The flea gets digested in your dog’s intestine
- This releases the tapeworm, which hatches and attaches to the intestinal lining
- The cycle continues as the tapeworm matures and releases segments
This is why flea control is ABSOLUTELY ESSENTIAL for preventing tapeworm infections!
Secondary Transmission Route: Rodents and Other Small Animals
Some species of tapeworms (particularly Taenia species) use different intermediate hosts:
- Mice
- Birds
- Rabbits
- Other small animals
In this case, your dog can get infected if they hunt and eat these infected animals. This is more common in rural areas or with dogs that have hunting instincts.
Signs Your Dog Might Have Tapeworms
How do you know if your pup has picked up these parasites? Look for these telltale signs:
- Rice-like segments in your dog’s poop, around their anus, or in their bedding
- These segments might be white and moving when fresh, or dried and yellowish
- Your dog scooting their butt across the floor (though this can also be caused by anal gland issues)
- Licking or biting their rear area
- Segments in vomit (less common)
- Weight loss (in severe cases, especially in puppies)
I remember when my neighbor’s beagle had tapeworms – she noticed what looked like “moving rice” in the dog’s bed and freaked out! That’s actually one of the most common ways pet parents discover these parasites.
The Zoonotic Question: Can You Get Tapeworms From Your Dog?
This is something many of us worry about, especially if we have kids. The good news is that you cannot get Dipylidium caninum (the most common dog tapeworm) directly from your dog.
For humans to get infected:
- A person would need to swallow an infected flea
- This is rare but has been reported in children
However, there are more concerning tapeworms like Echinococcus that can pose a serious threat to human health. These are less common but more dangerous, causing a condition called hydatid disease with cysts forming in the liver.
Breaking the Cycle: Prevention is Key
Now that we understand HOW dogs get tapeworms, we can focus on prevention:
1. Aggressive Flea Control
This is your number one defense! Without fleas, the common tapeworm lifecycle is broken.
- Treat all pets in the household with effective flea preventatives
- Use monthly flea control products (collars, topicals, or oral medications)
- Treat your home environment and yard for fleas
- Vacuum frequently and wash pet bedding regularly
2. Limit Exposure to Wildlife
If you have a hunter on your hands:
- Keep dogs leashed during walks
- Supervise outdoor time
- Discourage hunting behaviors
- Clean up dead animals in your yard promptly
3. Regular Deworming
- Follow your vet’s recommendation for deworming schedules
- Many heartworm preventatives also help control some intestinal parasites
- Dogs who hunt may need more frequent deworming
4. Good Hygiene Practices
- Clean up after your dog promptly, especially in public areas
- Dispose of waste properly in sealed bags
- Teach children to wash hands after playing with pets or outdoors
Treating Tapeworm Infections
If your dog does get tapeworms, don’t panic! Treatment is generally simple and effective:
- Prescription deworming medications (tablets or injections) from your vet
- The medication causes the tapeworm to be digested in the intestines
- You typically won’t see tapeworms passed in the stool after treatment
- These medications are very safe with minimal side effects
Important: Over-the-counter dewormers vary in effectiveness. The most reliable products are prescription-only from your veterinarian.
Remember that reinfection can occur in as little as two weeks if flea control isn’t addressed! If your dog keeps getting tapeworms, it’s almost always due to ongoing flea exposure, not medication failure.
The Different Types of Tapeworms
While Dipylidium caninum is most common, there are other tapeworms that can affect dogs:
| Tapeworm Type | Intermediate Host | How Dogs Get Infected | Notes |
|---|---|---|---|
| Dipylidium caninum | Fleas | Ingesting infected fleas | Most common type |
| Taenia species | Mice, birds, rabbits | Eating infected prey | Common in hunting dogs |
| Echinococcus | Wild rodents | Eating infected rodents | Can cause serious disease in humans |
My Final Thoughts
Understanding the tapeworm lifecycle might seem gross, but it’s super important for keeping both your pet and family healthy. The good news is that with proper flea control and regular veterinary care, tapeworms are usually easy to prevent and treat.
Don’t forget that if you do spot those rice-like segments, get your pup to the vet for proper diagnosis and treatment. And remember – the deworming medication alone isn’t enough if you don’t address the flea situation!
Oh, and next time we’ll talk about something less creepy, I promise! Maybe something about cute puppy training techniques or the best dog-friendly hiking trails. Until then, keep those flea treatments up to date!

How Do Dogs Get Tapeworms?
There is a cycle through which dogs get tapeworms. Unlike other parasites that dogs may get from exposure to an infected dog’s feces, dogs can only get tapeworms by ingesting a host (most often an adult flea) that has tapeworm eggs inside it.
There are a few ways a dog might ingest a flea, such as self-grooming, or grooming a dog or cat housemate. Other animals that can potentially transmit flea eggs include birds, rabbits, or rodents. Once digested, the tapeworm eggs settle into your dog’s small intestine. There, the tapeworm will develop into an adult.
The adult tapeworm is made up of lots of small segments, each about the size of a grain of rice, called “proglottids.” Adult tapeworms usually measure anywhere from four to 28 inches in length. As the tapeworm matures inside the dog’s gut, these segments break off and end up in the dog’s stool. Since these segments contain tapeworm eggs, the cycle will begin again, with a new host and most likely a new recipient.
Can Tapeworms be Passed Along to Humans?
Tapeworms can be transmitted to humans, but the risk of infestation is very low—you’d have to swallow an infected flea or, in the case of some species of parasites, via the accidental ingestion of feces that is carrying parasitic eggs. Children are most prone to this, since they’re more likely to be outside playing in grass, parks, and other areas where dog waste might be left.

FAQ
How likely am I to get tapeworms from my dog?
Can you touch a dog with tapeworms?
It’s OK to touch a dog with flea tapeworms since you can’t be directly infected by a dog.
Do I need to clean my house if my dog has tapeworms?
Can tapeworms live on bedding?
Tapeworms. These parasites are usually transmitted through the ingestion of infected fleas. If your cat has fleas and sleeps in your bed, there is a possibility that tapeworm segments, which look like small grains of rice, could end up on your bedding. While direct transmission to humans is rare, it is still a concern.
