Can Fatty Acids Cure Cocker Spaniel’s Itch?

Q. I know you mostly answer questions about human problems but I have three pedigree cocker spaniels with dry skin. They scratch all the time but have no fleas.
I have tried conditioner and baby oil on their fur and vegetable oil in their food, which just made them sick. Is there anything I can give them to improve their skin?
A. Our veterinary consultant says that cocker spaniels are susceptible to skin problems. Itchy, flaking skin may respond to a dietary supplement with the proper ratio of omega-3 to omega-6 fatty acids. One product is called 3 V Caps and another is called Derm Caps. You may need to consult your vet for access. Another option to try is safflower oil, starting with one-fourth teaspoon in the day’s food ration.
