Intestinal worms such as Roundworms, Hookworms, Whipworms and Tapeworm are common parasites that are easily contracted by dogs through contaminated faeces, soil and dead wildlife. Treating your dog with a broad spectrum intestinal wormer every 3 months is essential. We recommend Drontal AllwormerParagard or Endogard. Puppies should be wormed every 2 weeks until 12 weeks old and then once a month until 6 months. From 6 months old a regular 3 monthly deworming program should remain.
