Who would tell the police or whoever? Seems like a don’t ask don’t tell kinda deal... otherwise no way around it

You could use someone else’s dog as a bait and switch. Yep, good old Rusty here...

Or wait till another friend gets a pup and use their paperwork. It all depends what you want to get around. If you’re worried the vet will talk, just take them to a fat city or different state, and be like oh yeah I’m just staying here for a bit..
