My husband and I have been having daily discussions about the safety of elk antler chews since Christmas. So we agreed to ask our vet. and accept and abide by his opinion. He said no way would he let his dogs have them, and especially considering the way our Bulldogs chew, the possibility of shards getting lodged somewhere. So we're done with the antlers, LONG LIVE NYLABONES!!! Just thought I'd pass this information along.
