Fatty acid supplements are used in dogs and cats to relieve itching associated with allergies, add luster and improve the health of coat and skin, and reduce inflammation associated with many conditions. Often the pet will need to take the fatty acid supplement for 2-3 months before a positive effect is seen. Overdosage can result in vomiting or diarrhea.
