Hi Mia’s- An LID is a “Limited Ingredient Diet” which is exactly what Eukanuba Dermatosis is. I concluded that your dog could eat fish given that the main source of animal protein in the Eukanuba vet food was “fish meal”. The foods I’ve suggested and link I provided are other foods with limited ingredients using the main carb source (potato) from the vet food and the main animal protein source (fish) from the vet food. As long as she doesn’t react to any of the other carbohydrate sources in those limited ingredient foods, they could be valid, less expensive options as a subsitute for the Eukanuba prescription food.
