Quality + Healthy + Natural

The inventor of this product is a Holistic Vetenarian who really understands Nutrition. Liver is a necessary supplement, and we love that this is freeze dried

The inventor of this product is a Holistic Vetenarian who really understands Nutrition. Liver is a necessary supplement, and we love that this is freeze dried. Used to buy frozen grassfed liver at Sprouts...so messy and stinky. Now, we just soak this in bonebroth for 3 minutes and add it to Pennys breakfast meals ;)

Very Healthy!

Our dog, Baylee, has some mealth issues that prevent her from eating carbs. These are a good snack for her ans they are 100% liver. Just not too many at one time
