There's a Labrador in my house and I don't know where it's come from. DH appears to of left the back door unlocked by mistake, but it was shut? He's at work and knows nothing about it, I've just got home from work and I have acquired a dog. Collar but no ID tag. What is going on?! How did it get in?! Can labradors open and close doors? My little King Charles cavalier spaniel seems to think he's his new best friend so has obviously enjoyed this unplanned play date (thank god a friendly dog decided to break into my house and not an aggressive one) no idea how long this lab has been here but house has been empty besides our dog since 11am. Someone please tell me how this is possible. I'm baffled. Waiting for DH to get back with the car so I can get him to a vets before they all shut and see if he's chipped.
