One of my cockers actually digs holes in the plaster board in my house. She didn't chew it which makes it near impossible to stop. She does it if she is left in the house herself. We tried bitter bite stuff and that did no good. We thought she was really bored, so I convinced my hubby to get another puppy (yes he must be gullable) - that worked for a short time - then she started again.
It seems to get worse when she is going into season and she can dig 5 wee holes all round the kitchen walls in a very short space of time.
We were at our witts end - she had eventually managed to get right through the plaster board and left a gaping hole ...
To solve this, we went to Homebase and bought some strips of light white boarding stuff. We prop this in front of the walls before we go out and chuck in the garage when we get home and it has worked a treat. She can't get at the wall even if she tries.
Cant believe that I spent money replastering and touching up the damage when a few boards would have solved the problem much sooner
