[Dog_Obsessed]

Thank you so much for adopting! I agree that both Orijen and Acana are great foods, and that you should transition slowly. Get some of the food she was eating at the shelter/foster/previous home to use during transition. Also, I would suggest rotational feeding, since no food is perfect. Here is some more info on that: /frequently-asked-questions/diet-rotation-for-dogs/
Always transition slowly with rotation as well. Good luck!
