Verm-X is a 100% natural formulation that controls intestinal hygiene whilst being gentle on the gut and digestive system. Verm-X Crunchies for Dogs are designed to be fed every day throughout the year. This means that you do not need to buy additional reward or treat products for your dogs as the Verm-X formulation can act as a traditional treat whilst functioning as a continual intestinal hygiene control. Feeding instructions: Feed every day throughout the year. For small breeds (e.g. Jack Russell) 2 Crunchies per day. For medium breeds (e.g. Labrador) 4 Crunchies per day. Large breeds (e.g. Newfoundland) 6 Crunchies per day. Puppies can be fed half the standard amount of Verm-X Dog Crunchies from 3 months of age. The full adult amount can be fed from 6 months of age.
