Eh… You may want to talk to your vet before switching your dog’s food suddenly. I learned the hard way that my dog’s allergic to everything and has violent diarrhea when exposed to food she’s unfamiliar with. It’s like white people and Taco Bell.
My dogs are spoiled brats. One of them half the time will turn her nose up at anything I give her, only accepting some of what I’m currently eating, even if what was given her is the same or better than what I’m having.
