After being told by all of the local Eukanuba Dealers that Premium Performance 30/20 has been discontinued, I called Eukanuba for information.
I was told that it is undergoing a bag/name change, and the former UPC is in fact discontinued.
The new name for Premium Performance 30/20 is going to be Premium Resilience 30/20. And it is the exact same formula as before. There are no formula changes.
In the meantime, you could have a lot of trouble finding Euk 30/20.
There is none in stock locally, and I'm going to have to order it online.
