Worm control

Contributor(s): Eran Dvir, Ian Wright

Introduction

  • Dogs may harbor nematode (roundworm) and cestode (tapeworm) infections, most inhabiting the intestines. Lungworm (Angiostrongylus vasorum Angiostrongylus vasorum) is now endemic throughout most of the UK and growing in prevalence. Intestinal worms and A.vasorum are the main considerations for worm control regimes in UK dogs, however, worms may be present in other organs, especially in dogs traveling abroad.
  • There is an increased risk of importation of non-endemic species with the increase in the numbers of animals entering the UK under the Pets Travel Scheme (PETs Pet Travel Scheme ) particularly since there has been a recent relaxation in the rules. Dogs traveling abroad will also be at risk of exposure to novel worms such as Dirofilaria immitis Dirofilaria immitis and Spirocerca lupi Canine spirocercosis and Echinococcus multilocularis Echinococcus multilocularis.
  • Some worms carried by dogs have zoonotic potential such as Toxocara canis Toxocara canisEchinococcusspp and Ancylostoma braziliense Ancylostoma braziliense. Worm control programs should identify dogs at high risk of transmitting zoonotic pathogens and risk be minimized accordingly.
  • Worm control centers on suitable anthelmintic regimes and environmental control.
