My Sheltie fortunately hasn't had any allergies yet but my Westie does and he had some pretty bad scabbing and a bit of itching. I switched him to Nature's Variety Limited Ingredient Diet which would put me out of house and home if he was a big dog but he eats less than a cup a day so I'll survive.
BUT! My local pet store that specializes in premium pet foods has been recommending Zignature for dogs that have allergies and they've been telling me that their dogs are doing great on it, even their picky eaters. Haven't personally tried it on my Westie though, don't want to fix what's not broken. They sell it at $11.99 for the small bag which is significantly cheaper than my $18.99 Nature's Variety bag.
