My veto had already told me about this necklace because my dog is allergic to pipettes and tablets, and the spray has only limited action, especially when the dog loves to go in the water! Returning from vacation, my dog was full of chips, I immediately put the necklace, and a few minutes later, bullets were already weakened, fleeing to the rear axle which is the furthest from the collar location . The next day there was nothing. My dog is very tolerant necklace, it is odorless, short it's perfect!
