Here is what Dogfoodanalysis.com says about Blue Wilderness
6 Star food (out of 6 stars)
Four of the top five ingredients in this food are named meat products. The first of these is meat inclusive of water content (about 80%) and once that is removed it is likely that these ingredients would be more accurately placed somewhat further down the ingredient list (ingredients are listed in order of weight). However, since this is followed by three meat meal ingredients, we can have fairly high confidence in the level of meat content of the food, although the calcium and phosphorus content of the food throws some doubt into the equation.
This is an entirely grainless dog food. The major carbohydrate source is potato starch, which is primarily a thickener. The food contains a good range of probiotics and fruits as minor ingredients.
This food is excellent in containing only a very small amount of grain. Grains are not a natural part of a canine diet and it is pleasing to see dog foods on the market that exclude grains completely from the diet. This is a more natural food concept and combined with a complete lack of any low quality or controversial ingredients is the reason this food is placed in a class above the more conventional form dry dog foods. Some lingering doubts about the meat content meant that a 5* rating was considered for this food, but overall it slips into the 6* category.
The only caution we would make on this food is that the high protein content may make it suitable for adult dogs only, particularly in the case of large breeds.
