I have lab and she always needs to have something in her mouth. That's why they say that labs are "mouthy"! When not walking around with a toy (her stuffed badger is her favorite), she holds her "blankie" in her mouth. I think it must be comforting to her. I attach it to her collar so she doesn't swallow it! (she has had it quite far in at some points and appears to gag momentarily). I do take it off when taking her for a walk because it rubs on the ground and I am always worried that it may pick up some fertilizer or other residues that can be poisonous to the dogs as they later chew and suck on the tab.
