Hi thanks for reply He does not appear to be in any pain . We tried to just walk him.. but he does still limp . this is variable, sometimes more pronounced at other times not very noticeable . More recently he roles around a lot on his back . If you scratch his back allsorts of reflex's occur ,. he shakes himself his hind leg becomes active as if he is scratching himself and so on . There is no pain as far as we can see .. He appears to enjoy the stimulation ..Do not know whether it is related to his left front leg problem or whether it is something else.??
