That's the only way i can describe it really. Just found him in the garden chewing part of a brick. He also likes flooring - has removed parts of the laminate either side of my desk - and plaster/wallpaper, he has stripped the corners of the walls beside me. Why around me?
This morning I got up with him, fed him, gave him a kong with some treats in, and his toys (what remain of them) and immediately he finished all that he started on the walls and flooring. I had to bring him inside because he was looking for bricks and stones in the garden.
Literally he will come indoors from a long walk and start on the walls/floors - this has been getting worse this past week. He cannot have a toy for more than a few minutes without stripping it down into bite size pieces, I've been buying toys meant for massive dogs and he either ignores them or gets to work in making them a choking hazard for himself. If its not life threatening, he doesn't want it.
I assume he's finished teething. He usually only does this when one us is around, its rare he will destroy anything if the house is empty. So is it boredom? How bored can he be?
