It depends which formula you are wanting to use,as the only okish versions i saw was the puppy
wellbeing and the sensitive formula,and even then there are many better foods available than this brand.
I tend to avoid foods with ingredients that have or start with:
Cereals, meat and animal derivatives (min 14% chicken, min 2% meat juices),with antioxidant and colourant EC additivesRice, maize, poultry meat meal, soya bean hulls, Dogs who eat this one will be getting a bowl of mostly rice,maize and soy everyday

But if ingredients such as these dont bother you or your dog,go for it :)
