Biotin is B-vitamin that is water-soluble and is necessary for the proper functioning of a horse’s glucose and fat metabolism. Biotin is also essential for the epidermal tissues located in the horse’s skin and hoof wall. Horse that lack biotin often have cracked, brittle hooves, chronic laminitis, or dull coats.

When bridled horses toss their heads up, they are typically resisting the bit either due to a large hook or interfering wolf teeth. Wolf teeth can also cause a horse to be inflexible in the jaw to resist the pain of the wolf teeth contacting the bit. Since wolf teeth can cause pain and poor performance, they should be removed while the horse is young.
