Just to let you know Charley has been having one a week now - after his training on a Sunday

we take out of freezer on a Fri night ( well mum or dad does as i live away ) leave in fridge until sunday lunchtime - we do reduce his brekkie on a Sunday as he has training treats at class and give him a smaller dinner too in the eve.
We havent attacked them yet with a rolling pin

the crunching of the bones does make me hold my breath though, but all seems well, no upset tummys, dodgy poops, bones have stayed " down " its just the mad half hr he has after having one - excitement i think and very proud of himself

He is a gentleman though as will " offer " us some drops it at our feet to see if we would like a "try " when we decline he takes it to bed and its gone within mins ! then does a loopy half hour lapping the living room and garden if the doors open - so i think he gives it the paws up ! and would thank COL himself if he could for giving me the courage to try them.
