Dog food recommendation

I have a German Shepherd and a Golden Retriever. They are both healthy and eight years old. I share these dogs with my ex. She decided to switch food from the Costco brand to Frommes Gold. I haven't seen any issues at my house, but the GSD has been throwing it up at her house.



Any recommendations for a new food. A vet tech had recommended a Purina premium brand sold at fleet farm but the ex got this stuff on her own. I'd prefer something sold at Fleet Farm or Sam's Club but am open.



Thanks, Max
