Merlin Collar 65Cm (pack of 2) by Calier is a medicated collar for large dogs that protects against fleas, ticks, and sandflies thanks to its active ingredient, deltamethrin (1.04 g per 65 cm collar).
It offers continuous flea control for 16 weeks, tick control for 6 months, and activity against sandflies for 5.5 months; it reaches its maximum effect after one week. It is a practical format (black collar that releases a white powder) designed to simplify your dog's protection without constant applications.
Use only on dogs (not on cats) and avoid in puppies under 7 weeks or animals with skin lesions.
Adjust the collar leaving space for two fingers, cut the excess leaving at least 5 cm, and keep the collar in its pouch until use.
Take precautions into account: deltamethrin is toxic to aquatic organisms (do not allow bathing in watercourses), prevent children from handling the collar, wash hands after placing it, and remove and consult a veterinarian if any skin reaction or unusual signs occur.
