For new food, we recommend a 7-day transition. Begin with a 75:25 ratio of old to new food on Day 1 and Day 2, shifting to a 50:50 mix on Day 3 and Day 4, and a 25:75 balance on Day 5 and Day 6. By Day 7, your pet can fully enjoy their new food. For treats, remember to feed them sparingly — they should constitute no more than 10% of your pet's daily caloric intake. Monitor your pet for any unusual reactions when introducing a new treat. Treats are not a substitute for balanced, complete meals.
