I just bought my first ever house (yay!)… and my first ever puppy (double-yay!). I’ll be moving in soon, and I had planned for Ellie to spend nights (and some days) in the Laundry room, which has a door to outside. I’ll need to install one of those pet doors in the laundry door to outside, but Ellie is a Rhodesian Ridgeback, and will grow to be 26" to the shoulder. A dog flap in a door for her could be big enough for a small adult to get thru as well, and of course that’s risky (burglary)!
The only thing I can think of is to secure the Laundry from the rest of the house, so make its internal door have a deadlock, and made of proper exterior door material. At least then all they can do is steal my washing machine and dryer and dog bed…
What do other people do?
