If your pet is already eating Harringtons regularly and you're simply switching between flavours within the same range, a gradual transition from one to the other is typically not necessary.

The core ingredients across the flavours are usually similar, which helps minimise any impact on your pet’s digestion.

When a gradual transition might be needed
If you’re unsure or your pet has a sensitive stomach, you can transition slowly to the new flavour or variety over 7–10 days. 

Follow this simple guide for switching your pet’s food:

• Days 1-4: Mix 20% new food with 80% of your pet’s previous food
• Days 5-7: Adjust the mix to 40% new and 60% previous food 
• Days 8-10: Transition to 60% new and 40% previous food
• Days 11-13: Increase to 80% new and 20% previous food
• Day 14: Fully switch to the new food
