Whenever you need to switch your dog over to a new type of dog food, it’s always best to transition slowly. With Just Right, it’s no different. They suggest making a gradual transition over the course of seven to 10 days. Start by adding a little bit of the new custom blend to your dog’s existing diet. As each day passes, add a little bit more of the new blend and less of the old dog food. Slowly, you completely replace their old dog food with the new custom blend. This way, your dog’s digestive system has plenty of time to adjust to the new set of ingredients. If your dog has any sensitivities, it’s best to incorporate your veterinarian’s expertise when transitioning to the Just Right blend.
