When we calculate the amount of food your pet needs, it is based on calculations that estimate the average amount a pet of similar weight, activity, and age might need. This means that we may have to make adjustments with certain pets! For pets who are losing weight, we recommend increasing the amount of food your pet is consuming by no more than 10%. Monitor their body weight over the next few weeks. We also recommend checking in with your veterinarian to rule out any potential health concerns.
