Roundworms don’t just exist in puppies—they can live in adult dogs, too. And if you’re a dog owner, this is something you should know about. Roundworm infections are one of the most common intestinal parasites that affect dogs, and they can have a serious impact on both your pup’s health and yours as well. So read on to learn all about roundworms in puppies and dogs, how to tell if your pup has them, and how to treat them. The good news? It’s easier than you might think!

What are roundworms?

Roundworms are parasites that can live in the intestines of puppies and dogs. Roundworms look like spaghetti, or white, thread-like worms. They are usually about 1 inch long and up to 1/4 inch wide. The most common species of roundworm found in dogs is Toxocara canis. Roundworms are passed from mother to puppies through contact with their feces during delivery or nursing, so it’s common for them to be more prevalent in puppies than older dogs.

Puppies and dogs can pass roundworms to humans.

Roundworms are a parasite that can be passed from dog to human. They are a common parasite in dogs, especially puppies. Adult dogs rarely have roundworms because they develop resistance to the parasites as they age. Dogs can pass roundworms to humans, but this is less likely than it is for cats, who shed their eggs more frequently than dogs do.

Roundworm larvae can be transmitted by biting insects such as fleas and ticks, so keep your pet free of these pests by using safe topical treatments for flea and tick control on your dog. If you’re concerned about roundworm infection, we recommend talking with your vet about how often they should be treated before bringing home a puppy or dog from an unknown source.

How do you treat roundworms in puppies?

Roundworms can be passed from dog to puppy during the first few weeks of life. Puppies should be checked for roundworm larvae at birth, as well as at one week old and again at three weeks old. If a female dog is infected with roundworms and gives birth to litters continuously, she may pass the infection on to her puppies through their nursing mother’s milk.

If your puppy has roundworms, it’s also important that you make sure that he doesn’t get them again in the future: never let him play with other dogs without supervision (especially if they have been outside or have access to areas where others’ feces might be), and keep him away from places where there are lots of stray animals or wildlife (such as parks).

How do you treat roundworms in older dogs?

Roundworms can be treated with either oral medication or by injection. Talk to your veterinarian about which method of treatment they recommend for your pet. If you are going to treat the dog yourself, it’s important to follow all instructions carefully — especially making sure that the worm larvae have been eliminated (killed).

If you know a young puppy has roundworms and is not being treated, don’t give it raw meat and eggs until medical treatment has begun. These foods may contain roundworm eggs that could infect other people in your family if they’re ingested by someone who hasn’t been treated yet.

Roundworms are very common in puppies and adult dogs. Don’t let your puppy play in sandboxes, and get treatment for your adult dog if you find worms in his poop.

Roundworms can be a problem if you have a newborn or young child, or if the puppy or dog has roundworms that he passes to humans. You should talk to your veterinarian about treatment options if you see roundworm eggs in the stool of an unneutered male dog (the most common way they spread) or if your pet has diarrhea with blood specks.


So there you have it: roundworms are extremely common in puppies and dogs of all ages. You should definitely check your dog’s poop regularly for any signs of worms, and make sure to get your dog treated right away if you do find any. And remember, the best way to prevent roundworms is by getting regular vaccinations for your puppy or dog; this will help protect them from these nasty parasites down the line!
