OptiPet Vermin collar for dogs

The OptiPet flea collar protects dogs of all breeds from fleas, ticks, mosquitoes, and autumn grass mites. The collar is effective for approximately 4 months, even when wet. Additionally, the collar provides a pleasantly fresh scent and has fur care properties. The length of the collar is individually adjustable. It is worn alongside the regular collar. Open the packaging just before use and place the collar loosely around the dog's neck, cutting off any excess length and securing it. There should be enough space for two fingers between the collar and the neck. For growing animals, make sure to occasionally loosen the collar. The collar reaches its full effectiveness after about 5-7 days. Do not use on sick or recovering dogs or on young dogs up to 12 weeks old. Dispose of used collars properly.
