We got some over a year ago now, still got them knocking around the house.
When we first got them the boxers both thought they were something special so we had a few 'disagreements' over them and had to give it separately - hopefully Coco and Rex will be more polite with each other though!
From what I remember, the first time I gave it to them they spent about an hour chewing on them, the next time half an hour, the next time 10 minutes, after that no interest really.
Ruby spends maybe 5 minutes on them every now and then, Roddy & Jakey ignore them completley.
Be interested to know what your 2 make of them.
