Because of the issues we have had with Edi and kibble before, we were seriously nervous about switching up his kibble. We were not looking forward to dealing with daily upset stomachs we worked so hard to eliminate. So we decided to switch out slowly.
While typical kibble transition calls for a 10-day switch, we took nearly 3 weeks to make the full switch. We pre-packaged Ziplocks with the different ratios. Ed gets 3 cups a day and we increased in quarter-cup increments (i.e. 2 3/4 old, 1/4 new; 2 1/2 old, 1/2 new...), feeding each increase for 3 days.
It was a slow switch, but having the ratios pre-packaged made it so much easier - and it was worth it. We had absolutely no issues in our transition.
