Directions:
Read entire label directions before each use.
It is a violation of Federal Law to use this collar in a manner inconsistent with its labeling. Place the Preventic® collar around the dog's neck buckle and adjust for proper fit. 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. The active ingredient is not an insecticide. Therefore use other means for the control of fleas.
