@Doomer Well, SCP stories usually don't end with the thing being destroyed, due to making the report essentially meaningless as a reader, since it essentially becomes a 'wait for Goku to beat the shit out of someone' moment. In universe, trying to destroy objects may lead to more dangerous objects. This is best shown by SCP-1609, which was a chair that teleported to whoever who needed a seat(Safe Class) to a pile of broken chair pieces which, if scared, will teleport into the provoker's body, causing death by internal bleeding(Euclid). This only happened because the SCP was thrown in a wood chipper. In this case, shooting any part of the SCP may just cause the dog to grow stronger and increase it's 'attack radius'. Which you know, is bad.
