New to the forum, so please forgive if this has been beaten to death. I couldn’t find much for a response to an older topic of Acana replacing the oats in their Singles line with lentils. Two of my dogs don’t do well on chicken, so Acana Lamb & Apple was wonderful. One has had numerous urinary problems in the past–Cal. Nat. seemed to send her ph off the charts. That’s when I switched to Acana Singles, and she’s been doing really well for the last year. The addition of lentils has me concerned and looking elsewhere. Are others concerned about this change? And, how will the change affect their rating on Editor’s Choice?
