In the past three days our 17 weeks old pup has taken to chewing things other than her toys. She has suddenly been climbing on furniture and picking things off tables to destroy. Tonight, worst of all, she unzipped and unpacked the filling from our rather expensive garden furniture cushions and pulled most of the buttons off. I think she ate four cushion buttons and half of a koala keyring toy too.
This was despite having plenty of toys around, plus the remains of several bones, and even plenty of digging opportunities.
Up until now she has been excellent in this respect - very trustworthy when spending an hour or two in the garden or living room by herself, i.e. with us elsewhere in the house, or out. Now, suddenly, it's as though we cannot leave her unsupervised for even a short time.
How should we respond to this?! What's happened to our smart, civilised pup? Will we really have to go back to confining our now rather big (13kg) pup in her pen when we are not in line of sight?! She has not been confined, other than during the night, since she was 9 weeks old, and has been superb until now.
