Intestinal parasites are extremely common in dogs of all ages, and most can't be seen with the naked eye, which means you might not know if your dog is infected.
Four different types of worms commonly infect dogs and puppies: roundworms, hookworms, tapeworms, and whipworms. Puppies are also commonly infected with a single-cell intestinal parasite known as coccidian. Adult dogs can become infected with coccidia as well, but many dogs develop an immunity to these parasites.
Dogs can become infected with intestinal parasites in different ways. Puppies often become infected with roundworms prior to birth or when nursing from their mother. Tapeworms can be transmitted if a dog swallows an infected flea (treating flea infestations goes hand in hand with treating tapeworm infections). Dogs can pick up hookworms and whipworms from their environment, often from the feces of infected dogs, or contaminated soil or water.
Some of the most common symptoms of worms in dogs included digestive upset (vomiting or diarrhea), gas, bloated belly (pot-bellied appearance), increased appetite, unexplained weight loss, weakness, and bloody stool or diarrhea. In puppies especially, intestinal parasite infections can cause anemia and poor growth.
If you suspect that your dog might have worms, bring him to the veterinarian for a physical exam and fecal test. Treatment is generally easy with over-the-counter dewormers for dogs. Some worms can be transmitted to humans (children are especially vulnerable), so it's important to keep your dog parasite free.
When choosing a dewormer for dogs, you need to know what type of worms your dog has, which is why the veterinary exam is so important. You can purchase a dewormer for specific types of worms, or you can choose a broad-spectrum product that kills many different types of worms. Dewormers for dogs come in several forms including tablets, granules, powders, and liquids, so talk to your veterinarian about the option that is best for your dog. Once you know what kind of dewormer you need, take a look at our top picks for the best non-prescription dewormer for dogs.
