I'm going to have a look in Tescos to see if they have any bones I can give to McKenzie, but I'm not quite sure what sort of bones to be looking for. I know you shouldn't give weight-bearing bones, but not sure what this means - is that any leg bone, from any animal? Does anyone have suggestions for bones they might have in Tescos that would be suitable? (I don't have a butchers) I'm after something that she can chew on by herself when I need to occupy her, so something long-lasting and nothing like a chicken wing that I have to hold. Thanks!
