6 month old lab puppy ( although not a pup to look at!) has found a bone of some sort on our walk tonight and has brought it home and is now sat on the floor enjoying it, in fact she hasn't given me a second look! God only know what it's from, it was just bone when she found it in the field and it looks like it's got a joint in the middle so not tiny? Should she be having this? I think it's actually mingung, she's so happy, I don't want to take it away if it won't harm her!
