How did you ever expect to get inside your house in the event y'all lock yourselves out accidentally otherwise (without the dog's "help")? We've always hidden a key outside somewhere eg, lock-box secured to (garage) doorknob, plastic key-box buried in flower pot, key left with next-door neighbor, or stowed away inside doghouse (fav!).

Looks like the dog is better trained than the humans.

when your pet is more equipped to be a human than you are...

Your dog takes his job as a guard dog very seriously.

I never understand people who don't carry house keys, because I dont understand feeling like one isnt needed.

You might want to look into a hidden key or a keypad lock.

time for new locks

I don't understand why you would NOT carry a key... what do you do in case you luck yourself out?
