"EM" stands for effective microorganisms, which are baked into the ceramic. This changes the environment of the dog, making it less attractive to ticks.
Cleaning: For heavy soiling, clean the EM ceramic beads with clear water so that they can fully unfold their effect again. 100% tick protection cannot be guaranteed.
Important note: The EM ceramic necklace serves as an accessory and is not a substitute for a dog collar.
