Just curious, how was your dog diagnosed with a chicken allergy? Or are you assuming…..

Nutrisca Salmon and Chickpea may meet your criteria, see chewy dot com for reviews and prices.
Check the search engine “allergies” I have posted a lot of information, maybe you will find something helpful.

Allergies can be broken down into inhalant, contact, or food allergy origins. Flea allergies, grass allergies, and environmental toxin induced allergies are the most common causes of skin conditions in Cairns. Allergies can be chronic or seasonal. They can be minor or severe in occurrence. They tend to become worse with age. Treatment is much better than in bygone days. Environmental controls, antihistamine treatment, and desensitization injections have made huge strides in the last few years”.
“Glucocorticoids should be used only as a last resort due to serious side effects. Diagnosis and treatment of chronic or severe cases by a Board Licensed Veterinary Dermatologist is recommended”.
