Has he never been ‘put in his place’ so to speak? Am lucky that Loki is quite responsive to the reaction he gets from another dog… if he is ignores – told to go away or similar – he will… equally he will play rough with a couple of labs that he always plays rough with… i have noticed that the other dogs don’t react differently to others – they always try to play rough – whereas Loki seems to adapt… I have no idea why he is differnt – I think I am lucky.
But my parent dog is very good at telling him what he can and can’t do… maybe max just hasn’t ever had that? :-\
Am sure others will have more helpful advice.
