Hey there. I'm in the exact same boat. We've had luck with Purina Pro Plan Focus, Sensitive Skin and Stomach.
We're still transitioning from the chicken/rice diet, so right now my dog (6 month old terrier mix) is getting about 33% kibble and 66% bland diet, but so far so good. A small bag of the Purina Pro Plan is available on Amazon, so it might be worth a shot. Best of luck.
