… This is so stupid it hurts my brain.

I actually tried to find laws relating to… stowing? carrying? transporting? a gun, in a holster, on a harness, on a dog.

I could not find any.

I very much hope this is completely legally dubious, but given the patchwork insanity of US gun laws… there might concievably be some kind of very specific situation where this would ‘work’ in some kind of legal sense…
