Hi LucyLu,
I personally feel each dog is different a bit like us.
I have 2 female bullies. One thrives on Royal Canin and loves it - the RC is Maize / Meat based. The other is more sensitive to it and after a bit of trial and error, we are now on James Well Belloved which is Rice based (have tried the turkey and lamb), which seems to agree with her much better, firmer stools, less gas and she loves it.
I bought my food in a local pet shop in a garden centre, they had a policy whereby you can try quite a few of the brands with a full refund policy. You just have to return it with some in the bag and you are then able to try something new. They have been really helpful to me, discussing the ingredients and benefits of lots of the ranges. I've not used AG, but I belive it is very good qulaity.
So good luck with your 'trials'. Let us know how you get on.
