Hi welcome,
you could try feeding him!!!!!
Ive got 3 terriers, always run the legs off them before they are left alone in house
and they have loads of toys and chew sticks to keep them happy, havnt chewed
a thing.............up to now
thanks for the replies. he does take some tireing out ive noticed ,i give him knotted hide bones to chew on but they don't
last long and don't want to be giving him too many incase it makes him ill
