Do not remove the collar from the protective envelope until just before application. Place the collar around the dog's neck and tighten it. Make sure two fingers fit between the collar and the neck. Cut off the excess piece leaving 5cm at the end. Check regularly 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 can affect organisms in the water. Thanks to the practical buckle, the collar is very easy to put on and take off. But the collar is water resistant and if it accidentally gets wet, this will not affect its function.
