Did you know that coat color can be influenced by diet? It is well-known that specific amino acid deficiencies can cause color changes in dogs' coats. An example of this is "red coat syndrome" seen in dogs with a deficiency in the amino acid tyrosine. And just as deficiencies can dull color, providing high amounts of certain key nutrients can produce more intense coat color.

The process involved in producing coat color is very complex, but by providing the necessary amino acids and some key minerals as "building blocks," we can see an improved the coat's natural color characteristics. The amino acids are converted into melanins, which provide each individual hair with its characteristic color. Minerals such as copper are cofactors in the color building process as well. By providing optimal levels of the nutrients that are involved in melanin production, we can see more intense coat color as a result.

Good general grooming and nutrition can lead to healthy skin and coat. Just as individualized grooming treatments can result in better coat health, specialized nutrition can make unique improvements as well. A diet with the proper nutrients can provide not only a healthy coat, but a more intense coat color.
