vitamin defiencey in my cocker

Question
what vitamin should I give my cocker spaniel for her skin condition?


Answer
Dogs seldom need vitamin supplements.  All but the cheapest chows have everything a dog needs for a healthy skin and coat and general health.  At most, some dogs may benefit from a teaspoon a day of ordinary cooking oil added to their food. Bathe her as little as possible, and rinse her well when you do. Brush her every day with a soft bristled brush.  

If she still has skin problems, you will need a vet's help.
