Intestinal worms are only a few millimetres long and can live off the contents of the gut, others attach themselves to the gut wall. These parasites feed from the nutrients in the dog's gut and from the dog's blood. Worst of all these intestinal worms can infect people (some tapeworms can grow up to 5 metres in length) hence the importance in maintaining a regular de-worming program for your dog to keep it worm-free.
Roundworm (Toxocara canis) is probably the best known of the intestinal worms. But if you also have cats in tghe home they should also be treated for cat roundworm (Toxocara cati) . Human infection particularly children generally occurs when contact is made the worm eggs which have contaminated the soil. A common problem is gardens or public parks which have snadpits. So ensure that you keep your sandpit covered and don't let your children play in the public park sandpits.Alarmingly the worm larvae can migrate through the human body and concern should be if they migrate to the eyes. As they can get behind the retina, where they can cause permanent damage to the child’s eyesight.
