My daughter’s golden retriever puppy, Malibu, has itchy skin, dandruff and supposedly a sensitive stomach. What is a good food for that? I believe she gets diarrhea on some foods. The dandruff can get really bad and she’s always itching and licking her otherwise normal belly. She’s about 6 months old. A happy crazy girl! She is currently eating purina proplan puppy for sensitive skin and stomach.
