ok, core i have tried in the past and it's way to fishy for these guys lol, they really are not fish fans, innova evo i have tried but not the one mentioned, it i will have to hunt down their products are not readily available here.
i did however get a sample of the turkey and rice by Purina from the farm supply, he seems to like it
this is just as a supplement anyways, his main kibble is California naturals but the odd time he enjoys turkey so this is a good compromise.
