Help my lab who is 20 months old as just started chewing at my door and radiator cover which is right by his basket while we are out, can't understand why he's started this as he goes out a lot each day.
Welcome to you. There are lots of reasons why Labradors chew things, but it's very much normal Lab behaviour! Here is a great article on the subject - http://www.thelabradorsite.com/how-to-stop-your-labrador-chewing-things/ It tells us that Labs chew for four main reasons - boredom, anxiety, relaxation/pleasure and habit. It gives lots of ideas on how to stop the chewing. Good luck
