Finally what I had feared would happen, happened. Went upstairs to take a shower while Hobbes was downstairs with dad; dad let him out on deck and completely forgot about him. I come back to dad merrily talking to bro in other room while Hobbes barking on the deck to be let in. That was Hobbes barking?! was my dad’s reaction when I told him he was waiting to be let in. This is why I always worry when we leave him with dad to run an errand and there’s no one else home. It was only a matter of time something like this happened, and knowing my dad if he was not in front of deck door, he probably will ignore him barking for an entire day assuming it is some other dog.
