Bitter bandages are from Genia, France. They are a high-quality cohesive bandage that is impregnated with Denatonium Benzoate that is a bitter-tasting repelling agent. Denatonium Benzoate is widely used for this purpose in products such as nail polish. This ingredient is harmless in all other aspects, but it does solve the problem of your pet or horse trying to bite the bandage off. Bitter bandages are 4.5m long, and available in purple only.
