My dog with environmental allergies and a sensitive stomach does well on Nutrisca Salmon and Chickpea https://www.chewy.com/nutrisca-grain-free-salmon-chickpea/dp/35033
See the reviews

BTW: Food allergies are rare, food sensitivities usually tend to show up as stomach issues such as diarrhea and vomiting, environmental allergies usually manifest as “itching”
Hopefully it’s a mild case, seasonal….if that’s what it is. Try bathing with a mild shampoo such as Malaseb, see the vet if it gets worse.
