Diet and skin disease in dogs and cats.

Watson, T.D.
An optimal diet is vital for maintaining healthy skin and coat. Nutritional deficiencies are now uncommon due to widespread feeding of complete and balanced pet foods. Deficiencies of zinc, omega- 6 fatty acids and some vitamins are still occasionally reported as a cause of skin pathology in pets. Supraphysiologic doses of vitamin A have been used in the management of vitamin A-responsive dermatosis in Cocker spaniels. Other keratinisation defects and seborrhoeic conditions may also respond to vitamin A. A placebo-controlled, double-blind, cross-over study recently demonstrated a clear benefit of high dose omega-3 fatty acids in the management of pruritus. Some data also suggests that a specific omega 6: 3 ratio may benefit pets with inflammatory diseases.

A look at how fozen chicken effect digestibility, bioavailability and body weight maintenance. The article illustrate the effects of the Purina proprietary technology on higher protein and fat digestibility, better absorption of essential fatty acid and higher bioavailability of some limiting amino acids such as lysine and arginine thanks to 14-25% of total protein content coming from chicken.

Talk about the importance of doing a complete nutritional evaluation of the patient before instituting a dietary change in any patient, especially an older dog or cat. The patient evaluation, the current diet, and feeding management should be included in this edvaluation. Many diseases in senior pets, as cognitive dysfunction, osteoarthritis, and obesity are “diet-sensitive”, meaning that diet can play a role in managing the effects of the disease.
