The new Preventic PLUS collar by Virbac kills and detaches ticks for 3 months PLUS it now contains an IGR that sterilizes and kills flea eggs for 3 months.
DIRECTIONS: Place the collar around the dog's neck, adjust for proper fit and buckle in place. Cut off and dispose of excess length. The collar must be worn tightly enough to contact skin and so the dog cannot remove it. Preventic is a good choice for tick prevention. Combine it with Frontline for double tick and flea protection. They are safe to use together. Or combine it with Advantage for excellent flea and tick protection.
