What you need to do is focus on the intermediate hosts. That means good flea control for every pet every month. The rarer tapeworms can be prevented by not allowing you dog to hunt and consume his own food (which most won’t do if they’re properly fed).
Tapeworms are disgusting organisms to be sure. They live and feed in the intestines. These worms consist of large numbers of segments in a row. The segments at the back of the worm contain eggs. These segments are shed in the feces, or that move out of the anus under their own steam. The shedded segments initially look like grains of rice that move and crawl. Over time the segments dry up and look more like sesame seeds.

Here’s the good news for all dog owners, and especially for those who have rice grains or sesame seeds on their pillows: Tapeworms are not directly contagious. Those grains and seeds are disgusting (and they are covered with nasty bacteria), but you and your non-infested dogs will not contract tapeworms by exposure to them.
Tapeworms require intermediate hosts. After the segments are passed in the feces or crawl out of the anus, they must be consumed by another organism — the intermediate host. The most common tapeworm, by far, involves fleas as the secondary culprit. The tapeworm then matures for a bit in the flea, and then is ready to infest any dog, cat, or human that ingests the flea. And yes, there have been documented cases of humans (mostly young children) who eat fleas and develop tapeworms.
Signs and Symptoms of Tapeworms in Dogs
Signs and symptoms of tapeworms in dogs vary depending on the severity of the infection, but often include:
Tapeworms rarely cause serious symptoms in healthy dogs. However, very young, very old, or dogs with compromised immune symptoms may exhibit more severe signs, like intestinal blockages. These can be fatal if not treated.
Tapeworms attach to a dog’s small intestine with their hook-like mouths. The rest of the tapeworm, however, is made up of small, flat segments called proglottids, each approximately 3-5 mm in length. An adult tapeworm can reach up to 8 inches in length.
You may notice segments of adult tapeworms in your dog’s poop. These segments look like grains of rice, and you might also see worms around your dog’s anus. Some dogs scoot to relieve the irritation caused by tapeworms. However, since scooting can also be a symptom of impacted or full anal glands, it is not a definitive sign of tapeworms in dogs.
Tapeworms in dogs are spread in several ways, depending on the species.
Common causes:
Dipylidium caninum, the most common tapeworm in dogs, is spread through an intermediate host: fleas. Infected dogs pass tapeworm segments in their feces, where they dry and eventually break open. This releases the fertilized eggs into the environment, where they are consumed by flea larvae. As these larvae develop into adult fleas, the tapeworm egg also develops. Dogs ingest fleas infected with tapeworms while grooming or itching. Once ingested, the tapeworms infect a canine host.
Other species of tapeworms can be found in wild animals. Hunting dogs, dogs that have access to small mammals like mice or rats, and dogs fed raw meat or offal may become infected with these tapeworm species.
Diagnosing tapeworms in dogs occurs when a veterinarian finds tapeworm segments or eggs in a fecal sample. If other clinical signs are present, like stunted growth or poor coat condition, ruling out tapeworms and other parasites are essential for an accurate diagnosis. Your veterinarian will examine your dog’s feces for evidence of tapeworm activity. He or she may also examine the anus directly to see if any worms are visible.
However, dogs pass tapeworm segments intermittently, not in every stool. This means that tapeworm infections are not always identified during routine visits.
You can help your veterinarian make an accurate diagnosis by bringing in samples of feces that have visible tapeworm segments. If you notice segments in your dog’s coat, bring those in, too. Once tapeworms are discovered, veterinarians use diagnostic tests like a PCR to differentiate between tapeworm species. This is important for determining the appropriate treatment.
Tapeworms in dogs are usually straightforward to treat. Deworming medications like praziquantel remove the parasites from your dog’s intestines, eliminating the infection. Other medications include fenbendazole, epsiprantel, and nitroscanate, depending on the species of tapeworm. In some cases, tapeworms may lead to other problems, like intestinal blockages. This might require additional measures to treat and stabilize the patient.
Tapeworm infection is usually diagnosed when the moving segments are seen crawling around the anus or in a bowel movement. Dipylidium tapeworm eggs are rarely released into the feces and are therefore not usually detected by routine fecal exams performed by your veterinarian. Because of this, veterinarians depend on you to notify them of possible tapeworm infection in your pet.

Treatment for both animals and humans is simple and very effective. A prescription drug called praziquantel is given, either orally or by injection (pets only). The medication causes the tapeworm to dissolve within the intestine. Since the worm is usually digested before it passes, it may not be visible in your dog’s stool. The drugs are generally well-tolerated.
Yes; however, the risk of infection with this tapeworm in humans is very low. For a person to become infected with Dipylidium, he or she must accidentally swallow an infected flea. Most reported cases involve children. The most effective way to prevent infections in pets and humans is through flea control. A child who is infected will usually pass proglottids (or what appears as rice) in a bowel movement or find them stuck to the skin around the anal area.
Although cats and dogs are rarely ill as a result of a Dipylidium tapeworm infection, the proglottids can sometimes be seen crawling near the anus or on the surface of a fresh bowel movement. Proglottids contain tapeworm eggs; these eggs are released into the environment when the proglottid dries out. The dried proglottids are small (about 2 mm), hard and yellowish in color and can sometimes be seen stuck to the fur around the pet’s anus.
Can Dogs Get Tapeworm From Other Dogs? | Wag!
Can humans catch tapeworm from dogs? The answer to this question is both yes and no, and in this blog I will explain why. First, let”s take a look at what tapeworms are and why they are a problem.
The name tapeworm is given to several species of parasitic worm, including Dipylidium caninum, Echinococcus and Taenia. Tapeworms live inside their hosts digestive system, attaching themselves to the gut wall with a hooked head. As food passes through the host animals intestine, the worm absorbs it and grows, thus depriving the host of essential nutrients. A mature tapeworm has a segmented body and each of the segments carries the eggs which continue the life-cycle of the parasite. The worm will shed segments of its body from time to time, and these are expelled from of hosts body with its faeces. When exposed to the environment, the worm segments can then be passed to another animal.
Dogs can catch tapeworm in a variety of ways, which means that pet owners need to be very strict in following a regular treatment with a dewormer One of the most common tapeworm, Dipylidium caninum, is passed to dogs by fleas. Fleas can carry tapeworm eggs, and if a dog accidentally ingests an infected flea, it can catch a tapeworm. Dogs can also become infected by tapeworm if they eat raw meat or offal, especially from wild animals such as deer.
Now that you understand how dogs catch tapeworm, let”s assume that your pet has somehow become infected by this parasite. Can you catch tapeworm from your pet and how? Actually, you cannot catch tapeworm directly from your dog, but you can become infected by coming into contact with tapeworm eggs. One of the most common routes of infection is through contact with an infected animal”s faeces, gardening, clearing ground or playing in a sandpit. Children tend to be more susceptible than adults because they touch their faces and put their hands in their mouths more often. Unwashed vegetables grown in soil where animals have passed faeces or where wild animals may have grazed can also carry worm eggs. In humans, tapeworm do not develop into mature worms, but instead can form a dangerous cyst which may need surgery to be removed. This means that it is really important to make sure that everyone from the youngest to the oldest member of your family follows good hand-washing and hygiene after working outdoors and playing or grooming pets. You should also be responsible about clearing up your dogs poop, both around your home and in your neighborhood to prevent the spread of disease.
