thanx for the info,i have been to the vets with him and he suggested the diffuser for the time being,he has improved,the vet said he has probably inherited it from his mother,,hopefully i won,t have to worry too much,although he also said that jasper had a dis located back leg,he does limp from time to time,and sometimes yelps for no reason,so maybe he gets more aggressive when he,s in pain,will have to check it out further,thanx again for all yor info,,by the way kelly,i live in kings heath m8,,
