I'd love to have a dog flap for my two, but they can't be trusted without supervision. Even though the majority of the garden is paved, they dig massive meteor size wholes in the flower beds.
So far we have had to wire the flower beds so they can't get into them, I have one area which should be a toilet area that is still available but they dig massive holes so deep they're almost through to next door!!! My partner spent Saturday burying bricks along the fence line so they can only dig a little way down in way of a deterrent!!
My only other worry with the dog flap is the other neighbour who teaches piano from home, she probably wouldn't appreciate Jovi's singing accompaniement!!
Anyone else have a problem with the digging (my two can manage 6 holes in the 10 minutes it takes to shower!)
