Gah! Stupid phone!
Anyway, It could be that Evo is too high in protein and/or fat and doesn't agree with her, especially if her previous food was significantly different. Toki used to get gas on Blue Buffalo Wilderness for puppies. She had a nice coat, good energy, and good poop but the gas was probably the only downside to that food. We went through a couple bags since she did pretty well with it but switching the kibble to something lower in protein pretty much stopped the stinky gas problem
hopefully others will have some good advice too
