My dog eats another raw food as her main diet. I find these Natural Instincts tubes are a great way to compliment her regular diet and allow me to add different proteins to mix things up. I like to get the duck because it is a fattier protein and it has organs, which her regular food doesn't have and those are important for nutrition. My dog is very lean and could see her ribs a bit too much for my comfort. Since I started incorporating the duck I have seen her gain a bit of weight, which is what I was looking for and not to mention she likes it a lot!
