I found this from 2007, so provided this information is still up to date I guess I know how long to test each new food. I only have Roxy on the Iams food for 5 weeks, so that was probably not enough. Too late now I guess, she's already into the new Acana food. I will be sure to keep her on the Acana for a minimum of 8 weeks before making a decision unless of course she gets considerably worse! I don't know why they call it Acana Lamb & Apple, should be Lamb & Oats imo.
Oh, I have to remember to not give Roxy any of the chicken treats I have! I will have to buy some lamb treats with no fish in them...or just use kibble. Yeah, there's an idea!
