I don't think it's a bad food. I think it's great compared to a lot of dog foods. But for me, it doesn't have enough meat in it. I personally prefer the grain-free dog foods.
These are the 1st ingredients of the Halo,
Chicken, Eggs, Pea Protein, Oats, Vegetable Broth, Pearled Barley, Chicken Fat (preserved with mixed tocopherols and citric acid), Whole Peas,
From dogfoodanalysis:
The first ingredient meat inclusive of water content which, once removed as it must be to make kibble, will leave these ingredients weighing around 20% of their wet weight. It is therefore likely that they are more accurately placed much further down the ingredient list.
Meaning even though chicken is listed as the 1st ingredients, once the water content is removed, it will actually be placed further down on the ingredient list, and since it's not backed up by another "meat meal" it seems the food doesn't have very much meat.
