I am feeding my boxer a somewhat specialized diet. She has to be on an extremely bland diet (gluten allergy), so I usually feed her a scoop of Buffalo Blue dry dog food, about 1/4 cup of rice, chicken, and a tablespoon of plain yogurt at each feeding. Is there anything else anyone can suggest that I could feed her to mix it up a little bit? I am a little scared to try new things since her stomach is so sensitive. But it is my understanding that a sensitive stomach is not uncommon for boxers. Any suggestions?
