A friend (who doesn't have dogs) popped in earlier with some treats for dc, and had also brought the dog a "collagen treat".
I've not come across them before and the internet brings up rawhide - the companies advertising them as a safe alternative to rawhide, and some people saying they're essentially still rawhide.
Just wondered if anyone here has any knowledge of them? Don't know whether to stick it in the bin or if it's perfectly fine.
