In general, we recommend following the gradual transition instructions below:
Days 1-3: 25% Sundays, 75% old diet
Days 4-6: 50% Sundays, 50% old diet
Days 7-9: 75% Sundays, 25% old diet
Day 10: 100% Sundays
Having said that, we know all dogs are different, so your dog may need a bit more time to transition fully, or they may be so excited for Sundays, they can transition really quickly! We always recommend sticking to the gradual transition as much as possible, so monitor your pup closely and give us shout if you run into any issues transitioning.
