So Blaze has been on Blue Buffalo for about a year or so. We trade the flavors from time to time and this time I purchased him "Lamb and Brown Rice with New Enhanced Formula." He won't touch it. Just sniffs and walks away. I added water and he barely picks at it. So we have cut out all treats, except for the occasional carrot. He is acting as playful as ever, he just won't eat! One of my co-workers said that her dog did the same thing with this new formula. I have also heard that PetSmart will take back whatever is uneaten and give a full refund. He's been doing this for a few days now. Any advice guys?? Thanks!
