If you didn't expect to find bones in it...you didn't read the label. Because it tells you EXACTLY what's in the food so you're aware of it.
I have fed my dog this food to put weight on him...worked wonders. I just manually smushed up the bones. This is NOT a bad food...it's a quality food. But like any other food, kibble or canned, it needs to be given properly or it will cause problems.
The object is to add things to the diet that you can't get in normal kibble (like a true meat product that you can actually SEE, instead of just assuming that it is what they say it is). It's great stuff, if it is fed properly...and quite honestly, I think you're blowing this out of proportion.
When I bought the stuff, the store owner told me EXACTLY what was in it (including whole turkey wings), and told me what I'd see (carrots, peas, etc), and when I went home, I read the label for proper feeding instructions. Nary a problem with my dogs.
Like I said, if you had read the label....
