Won't use again for my dog

Gave my dog terrible diarrhea. Still have the whole bag. I was told that's what she was eating at the rescue. Never use it again.

Picky Eater Approved

My dog's a really picky eater, probably my fault for feeding her so many different things when I adopted her. She refused to eat any dry food for the longest time without additives. This isn't a miracle food in the sense that she'll gobble it up at every meal, but when she does eat, she eats this dry kibble plain [a big accomplishment]. Her coat is shiniest and gut seems healthiest on this food so I'll continue with it, hopefully for the rest of her life :) I am a veterinary student interested in nutrition and will only buy brands that are backed by science and undergo feeding trials. I will warn you - this food is a lot bigger than the medium puppy food!
