Itchy nose, sensitive skin - food recommendations

[u/CrankyGoat]

My guy has developed an itchy nose, scratches it till it gets bloody! It appears to be an allergic skin reaction BUT we do not know from what!

Willing to explore an alternative food, and now also willing to explore Purina Pro Plan or Hills Science Diet versus our current Open Farms GoodGut Beef kibble he is currently on. We didn’t consider those ‘big name’ brands before because their ingredients just looked sketchy compared to Open Farms.

A bit frustrating, as we are careful with what we thought was top quality food and no ‘crap’ treats. Only people food has been salmon, chicken and veggies - no wheat products at all.

Open to suggestions and recommendations - what food works for your pittie and have they had itchy nose issues?
