With any food switch, there’s a chance that your pup’s stomach may get upset (if you ate the same thing every day and then suddenly changed your diet, you’d probably have some gastro issues too!) That’s why we include a complimentary bag of probiotics with your first order and recommend transitioning over a ten day period. We also provide specific recommendations for how to do that in the welcome kit that comes in your first box. If your dog has unusually soft or runny #2 for more than a few days, contact your vet as you would normally. And wash your dog’s bowl at least once a day to make sure there’s no bacteria in there that could make your pup sick.
