I know mistakes are made. But most of the time if they are actually raiding a place they actually have seen and verified that someone is hanging around an area before saying 'hey lets raid the house'. My cousin works with the special ops team in the city near us. I asked him about it and he's said they make sure to actually see someone go in and out of a place multiple times. The mail thing isn't accurate and they know it.
These aren't debt collectors. These are actual police officers that are going to raid the house. They have to check, double check and triple check before they raid a house. They can't just say 'oh look mail goes here that's the house'.
I know a ton of friends my age *25* and older who still have mail going to their parents home.
So if he has done something and legitimately does not live with you and you are just going off the 'his mail comes to our house' I really don't see a raid happening.
If he does live there and they have a real reason to raid other than his mailing address matches then even though you aren't there it's your responsibility to get your dogs out. You say you have a friend who can get them out. If you really do and this is a real concern don't wait, don't pray everything stays ok, call them and get your dogs out of the dangerous situation.
