To stop chewing, which can often be a first indicator of cribbing, applying sprays and pastes can help.
Things to Consider:
The right solution -- If one particular product doesn't stop your horse from chewing, consider another type that has a different taste. Some are hot to the taste, and others are bitter.
Easy Application -- Most products can be easily painted, sprayed or rolled on with ease, to cover your problem area quickly.
Multipurpose -- Products can be applied to numerous surfaces and structures, even trees, and won't harm them. Painted surfaces are also safe with these products.
