Changing Diets
Gradually transitioning onto a new diet will minimize the risk of stomach upset or other issues. In order not to overfeed – check the feeding guidelines on the new food and the recommended amount for the dog’s weight (assuming the pet has a good body condition score).
Gradually replace ¼ of the current food with the ¼ of the new food every 2nd day. After 7 days, the switch over to the new food is complete.
If a pet is susceptible to stomach upset, it may be beneficial to transition over 10 days.
