Attach the CatanDog's disc to the pet's collar. To guarantee effectiveness it should stay attached to the collar permanently including when you give your pet a bath or even if you have your pet x-rayed by your vet.

ATTENTION: CatanDog’s® Tag is not a chemical product and it does not kill the parasite, but only protects your pet from parasite attacks. Only apply the CatanDog’s® Tag to a clean pet with no parasites. It is best to attach the tag at the same times as the last chemical treatment. This allows the tag to become effective while the pet is still being protected. Activation can take between 7-20 days depending on the size of the dog. The tag must remain attached to the dog at all times. If removed the activation of the tag has to be recommenced
