That's the problem with research
Now, I can't feel comfortable feeding my girls any kind of dog-prepared item after reading about exactly what the terms on the bag could mean versus what you think they mean. Terrible.
My girls are on Honest Kitchen and Raw mixture diet for the last few months or so.
I have seen an interview done with some of the big wigs from dog food companies admitting that they use meat from dead, diseased, or dying animals in pet food, including foods sold in the US.
