At the moment my boy is on JWB grain-free version and Nature-Diet as a tasty addition and once a week home cooked food (meat and veggies).
Ill give Orijen a try sometime as well see if it will effectively ruin me or not
Ill also probably try Arden Grange Lamb version as its quite highly rated generally!
My boy has a bit of a sensitive stomach (but will eat anything ) so im trying to see what suits him best whilst at the same time trying to feed him the best I can (good quality meat, no cereals if possible, etc).

I would not give Pedigree though its pretty much junk as far as ive heard.
