hi, my pups are 14 weeks old and they are happily eating knuckles, wings and large ribs that i get from the butchers and they can be frozen if you get large amounts. Shame the raw didn't work out, mine have been on it for just over a week and it stopped their runs and they seem to be doing great on it. The only thing im not brave enough to do yet is leave them with the chicken wings to eat when no one is around just in case a bit gets stuck!!
