Food switch due to latest recall - Page 1

I have been feeding TOTW, but my bag was part of the production code recalled. Because of this, and ALL the many Diamond recalls over the years, I will now switch. My question is, with having to return the TOTW, I can't do the gradual switch--it has to be 100% switch--so what can I do to minimize the digestive upset?? I bought some plain yougurt, and I always add tripe canned. What else can I do? Thanks for your answers.

P.S. I am switching to Fromm Surf and Turf Grain Free

Canned pumpkin helps too..

My vet told me today that because I did the "cold turkey" switch to be mixing a bland diet (Boiled Hambuger and White Rice) in with the new kibble to go easier on the tummy.

I'm in the same boat as you, I just threw my TOTW out last night and bought a new food today. Earthborn Great Plains Feast.

I have done cold turkey switches before by using the simple dog foods.  I had to switch from Blue and chose Wellness Simple ( I chose the Duck formula for this).  
You can also add rice as mentioned previously.
