Piper's bag of dog food was running out and I believe that it is a good idea to switch proteins so I bought a new bag of Fromm Surf and Turf. She was on Fromm Duck and Sweet potato.
Well, let the below pictures show you which ones she liked better.
Before mixed together in the dog food bin: Bigger kibble is the duck, smaller is the surf and truf.
What is left in her bowl-- big kibble only.
I think I know which ones she likes better :)
