CatanDog's Medals are small and effective

CatanDog's plate produces (or) generates electromagnetic and scale waves

CatanDog's plate works without incorporating any battery, as it's not neccessary, the POWER supply is the "earthly magnetic field" and the animal motion in it, cutting in such a way the flow lines, and, thanks to "Lenz Law" producing "Foucault" currents of extremely small power but enough to activate the CatanDog's disc, that acts as a passive resonator.

The CatanDog's disc is an Aluminium disc “charged” with escalating waves that repel fleas and ticks and is designed for external use.
These escalating waves create a protective field, driving away parasites and stopping new ones being hosted by your pet.

CatanDog's is eco-friendly, it contains no chemicals and is water resistant. Its effectiveness is due to a revolutionary protective magnetic field system that is proven scientifically.
