Can You Visually See Worms in Canine Feces?

Even the best-raised puppy can end up with intestinal parasites, the most common of which are tapeworms, roundworms, whipworms and hookworms. Depending on your dog’s age and condition, the presence of worms may not be apparent, especially if he doesn’t have many of them. Eventually, if the infestation isn’t treated, your dog will show signs of the worm burden he carries by becoming ill. In some cases he may also pass worms that are visible in his feces.

Visible Worms

Both tapeworms and roundworms may make their presence known when you spot some of them in your dog’s stool. Tapeworms come out in segments that look like grains of rice. They typically stick to the area around the dog’s anus or fall and land in his feces. Each segment is packed full of worm eggs and may or may not be wiggling when you see it. Roundworms are generally bigger, look like strands of spaghetti and can be as long as 5 inches.

Not Visible Worms

Whipworms and hookworms are generally too small to be seen with the naked eye and must be diagnosed by microscopic examination. A routine veterinary screening will find these worms. If the dog doesn’t get regular checkups, these worms are usually only found if the dog gets sick and begins passing blood or vomiting. Always consult an experienced veterinarian regarding the health and treatment of your pet.
