Each dog is different, so there will be a bit of trial and error. Daisy is a rescue and was very stressed when she came to us, and had a runny tummy fairly often. Lily's Kitchen suits her best, however, previously I have had good results with Naturediet, and I believe they now do a kibble as well as wet food. Also used Burns for my boys and ex-breeder, they all thrived on that. Burns and Lily's will send you samples if you don't want to invest in a big bag of food straight away. Can't comment on AVA, I have never noticed that one before.
