I have some question regarding salmon oil for dogs.

I have two yorkies Bella a girl and 9.5lbs and Polo a boy 5.5lbs
I would like to start supplying them with salmon oil in there food
Bella is always bitting her paws and scratching a lot so I thought it might help I ordered Grizzly Salmon Oil in a small size on amazon. It has not arrived yet but now I am seeing that when you give salmon oil to dogs you need to give them Vitamin E is this true? Also how often should I give them salmon oil a couple times a week or everyday? Also Polo eats Ziwi peak Vension which is pretty much the same as raw it is meat and organs and it says it has vitamin E in it. Bella Eats Soild Gold just a wee bit and it says it has Vitamin E in it also, I am just wondering if there is enough in there food for me to not have to supply extra. And if I do need to supply Vitamin E what foods could I give them that are healthy and full of Vitamin E?
