Is there a reason you are wanting to switch? I don't have anything personally against RC, some formulas are pretty good, and some are good for dogs with allergies, medical issues, sensitive tummies, etc. But if your dogs are doing well on Acana, I wouldn't personally switch. The only main complaint I've heard about RC is it causes itchiness in a lot of Yorkies. Oh and a lot of the formulas are really expensive. Most of them around here are between $20-$25 for a 3-4lb bag!! I used to buy Acana (5.5lbs) for $14.99. But some thrive on it -- so it all depends on the dog!
I just re-read, did not realize she was already on RC... if she is doing well on it, then keep her on it
