I think ACANA is a very high quality food and my guys were thriving on it.  They have been on it for about two years without any problems.  I was surprised when, out-of-the-blue, ALL four of my guys refused to eat it. 

  I knew that it was a fairly new bag, but wanted to make sure that it wasn't a freshness issue so I picked up a couple of sample size bags....they wouldn't touch it.  I can understand them getting bored with it, but it did surprise me that all of them decided that they didn't like it.  I really trust ACANA, but had to start my search for a new food.  I brought home a few samples for them and finally found one that all will eat (Fromm Beef Frittata).  It's a great feeling when all agree on ONE food....they love it, even our little rescue guy (and he seems to be the pickiest of all).   
Have any of yours had this reaction to ACANA lately?
