I would like to start feeding Leah sardines. Leah has allergies to yeast and a couple of other things. She is currently receiving shots for the allergies.
Because she is an adopted dog from a bad situation I am still going through the process of determining if there is a food allergy or not. I have had her for 8 months now and she has eaten NB Duck and venison formulas. So far, so good. I need to go back now and challenge the duck. Leah did not start out with a good diet so I had to start from scratch. She seems to handle food well so I don't anticipate a big problem with food.
I feel Leah needs to have more "skin support" and because my vet derm does not care for supplements I thought if I could try it in natural form would be my best bet.
How do I go about feeding it to her? I read many other previous posts and it seems to be that many people feed the fish 1 to 3 times a week. Because I would only feed this to Leah once or twice a week, will I be able to tell if she would allergic to it unlike when you feed something daily you see the reaction quicker? Should I feed her small portions of the can over a couple of days?
Also, I know that if I was to give her a fish oil capsule a vit. E should also be given, do I need to worry about vit. E with feeding the fish versus a capsule?
I know that giving her this fish a couple a times a week may not have the bigger benefits of being able to give her a controlled amount with a capsule, but for now I would like to try the fish feeding and see how it goes.
One more, if I was to try feeding Leah raw eggs in addition are there benefits she would gain to help her skin?
Thanks for any help or advice

. I am always looking for ways to improve Leahs conditions.
