Patiently At The Door
Butler knows the rules, he is an outside dog only.
Having the door ajar into the garage is still very tempting, he is on high alert wanting to check out why the door is open and if anyone is coming out and especially if that someone happens to have a kibble, a nibble or dinner with them.
Butler will stand guard at this open door for as long as it takes to find out why the door is open. Just in case he needs to sound the alarm to notify us humans that the door is not secure.
