Like Brit I have Pnut on Acana. He has been on it for about 2 years.. I have had him on everything under the sun! Blue Bufflalo, Royal C, Soild Gold, Natural Balance, Natures variety .. I THINK that's it. LoL
Not sure why non of those foods lasted with him, I mean those are all good food, Pnut doesn't do well with chicken based food, he is more Lamb, Bison, Duck and Fish. I had one flavor I dont remember what it was but the flavor was Venison, LOL OMG he wouldnt touch it with a 10ft pole!! I had to donate the food to my local shelter
The trick is to find something that works and stick to it!
