The best is to switch gradually to a new food by following the next example:
Day 1 | Day 2 | Day 3 | Day 4 | Day 5 | Day 6 | Day 7 |
New/Current | New/Current | New/Current | New/Current | New/Current | New/Current | New |
25/75% | 25/75% | 50/50% | 50/50% | 75/25% | 75/25% | 100% |
When you are currently feeding your pet dietary food, first consult your veterinarian to see if switching is possible.
