Overview of Roundworm in Dogs

What is Roundworm?

Roundworm is a medical condition that is usually caused by two different species of a parasitic worm. This worm will usually first be present in a dog's intestines, though may migrate to other body systems. Many dogs with Roundworm experience a Roundworm infection of the lungs, which leads to vomiting, coughing, and other symptoms.

Parasitic infections such as Roundworm may cause adverse effects on a dog's health, such as malnutrition, loss of appetite, and lethargy. Roundworm is currently the most common type of intestinal parasite that is diagnosed in dogs, and can sometimes grow to be up to 12 inches in length. In many cases, an infected dog's feces may contain several worms, which is a good way to diagnose this condition.

What dogs can get Roundworm?

Since Roundworm is a parasitic infection, it is not specific to any particular breed or genetic type of dog. However, Roundworm is much more common in puppies, especially puppies that are under 4 weeks of age. At this age, a puppy's immune system is still underdeveloped, and they are susceptible to many different types of infections (including Roundworm). Some puppies may overcome a Roundworm infection on their own, but many infected puppies will require the use of Roundworm treatments.
If a puppy is born to a dog infected with Roundworm, the chances are high that the infection will pass from mother to puppy during fetal development. It is also possible for a dog to get roundworm through nursing from a female dog that is infected with Roundworm.

Can Humans get Roundworm?

Depending on the species of Roundworm, it is theoretically possible for a human to become infected with Roundworm. As most of the infectious Roundworm eggs are present in a dog's feces, it is very important to pay close attention to your dog's bathroom habits. Though ordinary household cleaners may not be effective in preventing infection, a solution of household bleach and water may help sanitize your infected dog's personal belongings, to help prevent cross-contamination.

Is Roundworm Fatal?

Roundworm may only be fatal to your dog in very extreme cases, or if your dog has been weakened due to a previous medical condition. Roundworm may inhibit proper absorption of nutrients for your dog, and may sometimes even result in intestinal blockage. However, these situations will usually become apparent with enough time for the proper veterinary treatment to be performed.
