demands for protein comes from hair and fur, which can use up to 30% of

 a dog's daily protein intake.

They also supply the fatty acids that are important building blocks for

 important substances and essential to maintaining normal, healthy cells.

         Carbohydrates: can be broken in the digestive system and converted to glucose

which could also be used as source of energy. Carbohydrates in the for of

whole grains can furnish iron, minerals, fiber as well as other beneficial nutrients.

       Vitamins: Organic substances, or synthetic derivatives are required for normal

body functioning. They are important in the conversion of calories

to energy, improving immunity and other body processes.
