Hi im the proud owner of a Jack Russell. His name is Lenny and although i love him dearly he has been causing me a few problems. Each time the postman arrives he eats my post (lenny not the postman). He also jumps and attacks the letterbox randomly throughout the day. Ive searched for a safe letter box for the inside of the front door but can only find wire cages which he will either pull off or pull out his teeth with. Has anyone else encountered this problem? If so how have you solved it? I would prefer to use an internal mail box and to be able to read my post!
