APPLICATION INSTRUCTIONS: Place this collar around the dog's neck, adjust for proper fit and buckle in place. Cut off and dispose of excess length. Do not allow dogs to play with cut-off excess. The collar must be worn tightly enough to contact skin and so that the dog cannot remove it. Activity against ticks starts within 24 hours and continues as long as the collar is worn (up to 90 days). Ticks present in the dog's environment that may reappear on the dog will not attach and will be killed in less than 24 hours. Replace collar when effectiveness diminishes. The effectiveness of the collar is not diminished by normal wetting such as rainfall, however, it is suggested that the collar be removed before bathing. This product does not control fleas.
