I'm intrigued to know who the 'experts' are who rate Orijen so highly - I remain a sceptic based upon (if nothing else) its protein content which seems far too high for a dry food, based upon the many years experience that pet food companies, not to mention AAFCO in the US have built up over the last few decades.
John Burns has shown over thelast 20 years that a low protein food can help in may common health problems of dogs, and resarch by (I think) Purina has beacked this up scientifically
