Added borage oil and vitamin H, the synergistic effect of the two makes the Yorkshire Terrier's coat softer and shiny. Adding French Royal's unique hair-beautifying nutritional complex makes the color of the coat more obvious. Add sufficient amounts of sulfur-containing amino acids (necessary for the synthesis of keratin) to make the coat healthier and more beautiful. Calcium chelators are added to bind to free calcium in saliva and help reduce tartar formation. The natural and unique fragrance satisfies the extremely picky taste of Yorkshire Terriers. Extend the life of Yorkshire Terrier and make it last longer.
