Roundworms are a common parasite in puppies and kittens, as they can be transferred through their mother or through contaminated feces. Other common internal parasites include tapeworms, hookworms, Giardia and coccidia. Dogs and cats can also be infected with external parasites such as fleas, mange mites, ear mites, ticks or a fungus known as ringworm.
It is important to routinely check your pet for internal and external parasites not only to keep them healthy, but also because some of these parasites can be transmitted to humans. It is especially important if there are any children, elderly, or immunocompromised (e.g., pregnant, ill) individuals at home.
