Bruce is nearly 8momths and his night time bed chewing is getting worse . He has gone through all the nice beds I've bought him so is now back in a plastic bed with old covers but even these get shredded on a nightly basis . Is there anything I can do to try and stop this . He doesn't chew anything during the day just on a night . He is no longer in a crate but in a small hallway on a nighttime and he is in there from about 11 till 6 . I do put various toys in there with him . Is he not getting enough mental stimulation or excersise or is it just a stage he will grow out of ??
