Thank you we got hold of the vet who attended to him eventually tonight. This dog is a prison service dog and so is not with us. The vet said he will ship him out in the morning for scoping and pssibly surgery if that is not successful. Fingers crossed all ok overnight all well so far. Thank you for your reply. I am a nurse and was worried the parafin although gentle would move the ball out of the stomach and then cause an obstruction.
