The Canishield® 1.04g collar for large dogs provides long-lasting triple protection against parasites. Kills and repels the mosquito that transmits leishmaniasis (Phlebotomus perniciosus) for 5 and a half months Kills ticks (Ixodes ricinus) for 6 months Kills fleas (Ctenocephalides felis) for 16 weeks. It is suitable for dogs from 7 weeks of age. The collar is odorless and waterproof, and is safe and easy to put on thanks to its adjustable strap. Deltamethrin, the active ingredient in the collar, is constantly released by the friction of the collar against the dogs neck. This forms a uniform protective barrier over the entire body of the animal through the skins lipid layer. The active ingredient never enters the dogs bloodstream. When fleas, ticks, or sand flies come into contact with Deltamethrin, they are quickly paralyzed and die. Although parasites proliferate in the environment as temperatures rise, the animal should be protected year-round. For best protection, it is recommended to apply Beaphar Canishield® before the peak of parasite infestation season. Instructions Do not remove the collar from the protective pouch until just before application. Place the collar around your dogs neck and adjust it. Ensure that two fingers can fit between the collar and the neck. Cut off any excess length, leaving 5 cm at the end. Regularly check that the collar is neither too tight nor too loose and adjust the length if necessary by tightening the buckle and sliding the collar into the correct position. We recommend removing the Beaphar Canishield® collar when your dog goes swimming, as the active substance may affect organisms present in the water. Thanks to the practical buckle, the collar can be easily put on and taken off. However, the collar is water-resistant, and if it gets wet accidentally, this will not affect its function.
