We had no problems at all with Orijen,
Wolfsblut food shows how important it is to have a very close look at the analysis and not to believe the manufacturer: If they follow German declaration law the list of ingediences has to follow the content in food. The part with the highest content has to come first, the one with the second highest second, etc. The third highest content in the lamb version is rice, there is one on the site with sweet potatoes at first place, very unusual feeding for wolves
Orijen now contains 80 % of animal sources and 20% vegetables and fruits.
If you take puppy or adult is not so important, but with adult you might get problems with Ca : P Balance with some brands. And high fat can be fatal with fast growing dogs. So with large puppy you are on the save side.
