I give to my dog about every 3 days. She loves them so much that she has even learned to recognize the white box when it is delivered and she goes absolutely nuts.

I have a 120-lb female lab/great dane mix and she loves these bones. They will usually last several hours and when hollow I can fill with peanut butter.
