Answer
Vegetable oil will not help itching.  There are special oils called Omega3 fatty acids that decrease the skin's sensitivity to allergens.  They are put into the food daily and they may take 30-45 days to start working. If the dog is very itchy, the best thing for him is a steroid shot to relieve him and to stop the self-mutilation. Have the dog evvaluated by your vet first.
