My poodle with allergies receives immunotherapy and does well on Nutrisca dry (fish) as a base combined with a homemade diet (see the link I provided in the Homemade Dog Food thread). She gets a fish oil capsule daily, too.
Her allergies are environmental (as most are) but she does have a sensitive stomach.
Often food sensitivities are referred to as allergies when they are not.
Allergies often show up around this age and tend to get worse with age.
