Dogs + Parasites

  • Owning a dog can be an extremely rewarding experience, but it also carries with it some responsibility. We hope these notes will give you some help.

  • Roundworms, nematodes or ascarid worms are intestinal parasites that live freely in the intestine, obtaining their nutriment from the partially digested intestinal contents.

  • The sarcoptic mite is responsible for canine scabies (sarcoptic mange). It lives just under the skin.

  • Tapeworms as their name suggests are flattened intestinal worms that are actually made up of many small segments about 3-4 mm long. Unlike roundworms which live freely in the bowel, tapeworms attach to the wall of the small intestine by hook like mouth parts.

  • Whipworms, Trichuris vulpis are intestinal parasites which are about 7 cm long. They live in the large intestine (caecum and colon) of dogs where they cause severe irritation to the lining of these organs.

  • Broadly there are two types of worms that cause problems in the dog, nematodes (roundworms),and cestodes (tapeworms).

  • Zoonoses are diseases which are transmitted from animals to man.
