My dogs are obsessed with these. I give them one piece each as snack before bed and they're like dog treat gold to them. They are light and crunchy and I like how they are all natural - just lamb lung as the sole ingredient. One of my dogs has food allergies, so this is extra important for me. They're not greasy or smelly, so no worries there either. I can't even tell you how many bags of these I have gone through and I will continue buying them. Highly recommended.
