Collar Merlin Antiparasitic Dog Collar 65 cm – 1 unit Calier

Merlin 65 cm by Calier is a medicated collar for large dogs that protects against fleas (up to 16 weeks), controls ticks (6 months), and hinders the feeding of sandflies (5.5 months) thanks to its active ingredient, deltamethrin (1.04 g).

It will reach its maximum effect one week after being placed; sandflies and fleas usually die and fall off within 24 hours, and ticks within 48 hours. It is a black collar that releases a white powder and is available in packages of 1 or 2 units.

Do not use this collar on puppies under 7 weeks old, on dogs with skin lesions, or on cats (deltamethrin is harmful to them).

Place it by taking it out of its bag just before use, adjust leaving space for two fingers, cut the excess longer than 5 cm, and periodically check the placement.

If you notice any skin reaction, remove it and consult the veterinarian.
