When transitioning from our old to new dry dog food recipes, we'd recommend a brief transition window of 5-7 days, especially for puppies since this is a new flavour. This helps ease the potential impact of switching to a different protein source on their sensitive tummies.
Moreover, since the recipes have undergone some adjustments and are now being produced at a different facility, there could be other external factors at play, like variations in cooking methods during extrusion, which might influence digestibility.
Note: This article refers specifically to the change in Barking Heads dog food range in October 2023, when new dry dog food products were introduced to replace and update the previous range. The new dry dog food products can be identified by looking for the 'Made in the UK' symbol on the packaging.
