last night benson , my 8 month old working cocker , bit my husband hard enough to draw blood , benson was asleep on the couch , and my hubby saw something in his mouth , he woke benson up , gently , and when he asked for the thing in his mouth , which turned out to be a mouldy old sock he had dug up from the garden , benson growled at him , not thinking that benson would actually bite , he tried to remove sock from his mouth and benson then lunged at him and bit him halfway up his arm , this is the 1st time he has bitten anyone , although he has been getting quite possesive over other things he has taken a fancy to , any ideas on what to do hes my 1st dog ever and i love him to bits , but its getting harder to trust him
