any ideas why and what I could do? our 1 year old black lab chews the back of car seats, bean bags, toys, she has just eaten a hole into a wall next to her bed, she has munched through sofa cushions and carpets. She ignores the chew toys we buy her. She gets walked every day off the lead, usually accompanied by a swim in the sea, she has a field behind our house where she can run at her leisure. She gets left in the house for 5 hours every day when I go to work in between school run, then she has our older lab for company. The chewing doesn't just happen during the day, but often at night as well as in I find stuff eaten in the morning. I'd be grateful for any advice!
