I switched to Pro Plan also. Like you, I was pretty hesitant. I am not thrilled with the ingredient list.......BUT if the "proof is in the pudding".....
Here are my Pro Plan munchers...
Brownie (PP Selects Salmon and Rice)
Rommel (PP Selects Salmon and Rice)
Ziris (PP Performance)
Piper (PP Selects Salmon and Rice)
Those photos are all within the last couple of weeks.
I have been very happy with the food, and I have fed just about every super premium food on the market, and RAW.
My dogs LIKE it (hit or miss with other foods) They keep weight on (again, hit or miss with other foods) They have nice coats, and seem to be overall doing well.
