Combination of kibble and raw. I rotate the kibble i use on a 1-2 week basis. The Kibbles I include in my rotation currently are:
Innova Evo
Timberwolf Organics
Orijen
Nature's Variety
I am curious to try Taste of the Wild, Innova Evo RM, GO, Wellness CORE and a few other brands.
As for the raw meat I will feed pretty much anything from beef to chicken to turkey to pork (although I am a little sketchy with pork) to lamb to venison to rabbit...etc
I also supplement with Fish Oil capsules and Glucosomine.
