I used to have an old dog that would eat anything. He'd always try to get the bait off the trap. Most times he just spring the trap and then lick all the peanut butter off bait pad. Sometimes he get it in the nose but a day or so later, he'd forget the pain and be right back at it. We weren't catching any mice because of it.
He couldn't get to the peanut butter in the tube traps, so he'd leave them alone after awhile.
If you want to make sure the mice don't come back, you should kill them after you clear the trap.
