i have a sal/bul/grey x sal and have had the same issues , patients and calmness is the key . no work just wait for the phase to pass , i found completely ignoring the dog got her interest . i think she maybe though she was in charge and by following/chasing and trying to catch her up was me approaching her and being subordinate , so i just gave up and thought bollocks to this and left her to it , her attitude to me changed and alls much better now (about 11mths at the moment) . skycat said in a previous article that most have a f##k you stage around the 7-12 mth age . good luck
