My first dog did the skirting boards and the end of the kitchen unit (formica and chipboard).. Jovi's making a big whole in the wall, which is an outside brick wall and not plasterboard (I think there's something fishy in plasterboard that they like).
We have made up a chilli, mustard paste and painted it on the bit he's chewed, so far no more damage to the wall!! I don't know why he's decided the walls tasty, as he has Neo to play with and when I leave them I give them kong challenges etc, but I think if they're going to do it, they're going to do it (unless crated continually)
It could be worse, my friend's cocker learnt to remove the washing machine drawer and completely destroyed it!!!
