gonna annoy some people here but i think they should be banned tbqh, but not altogether tho, just have the display's use them, im kinda lucky no one has started letting them off yet where i live but im dreading it, just got a new puppy a wk ago today, dunno how shes gonna take to them and im worried sick as my little minpin i lost over a yr ago was terrified, so yeah just keep them for dispays
