Calier Merlin Antiparasitic Collar Dog 48 cm – 1 unit

Collar MERLIN 48 cm by Calier, designed for small and medium-sized dogs: a medicated collar (1 unit per package) containing deltamethrin (0.77 g per collar) that provides protection against fleas for 16 weeks, against ticks for 6 months, and reduces feeding by sand flies (Flebotomus perniciosus) for 5.5 months; it reaches its maximum effect one week after placement.

Do not use on puppies less than 7 weeks old, dogs with skin lesions, or on cats. Remove the collar from the protective pouch immediately before use, adjust it leaving space for two fingers, cut off the excess leaving at least 5 cm, wash your hands after handling it, and avoid prolonged contact with children or allowing the dog to enter water bodies; in rare cases, skin reactions or temporary symptoms may occur, which usually resolve after removing the collar.
