I don't know the exact time span, but for a time, I fed the Hare-Today grinds... not knowing that they weren't 80/10/10. Sooooo, the new grinds that are 80/10/10 (with at least 5% organ being liver), the new grinds are a very good thing!
Ashlee (daughter of owner) that has taken over Hare-Today... has made some GREAT changes!
