It says on the label "Keep away from Children" but I recommend you keep it away from your dog as well!
Ryker was at my feet as I was doing some paperwork in my office. He had not one but two rawhide bones beside him. I heard him chewing away...then comes this loud PSSSST sound! Scared both him and me! Well, you know what he was chewing on. I called the Vet who said he should be fine and he looked fine except for the chagrined look on his face!
