Horses

EM ceramic anti-tick Horse cuff is a great natural alternative, it can be as effective as any tick treatment found on the market  but without the toxic chemicals and side effects, making it safe, especially for horses with allergies and sensitivities. 
These work in the same way as the dog collar.  
From my customers experiences is best to have two. It is very important to keep the cuffs on all the time and keep the beads clean.
