Does anybody have any tips / practical ideas to help reduce or better still, resolve the aggression my 4 year old Labrador has when coming to the end of the food in her bowl at feeding time? She transforms from being a little angel to sometimes quite scary. She has never bitten. She is a labrador who would left her own devices inhale her food. I've tried a few things to reduce this. Currently with good weather I place a food in various places in the garden and see loves to seek it out. Seldom is there any aggression when she's fed this way. Indoors she is fed 5 small portions one after the other but is asked to sit and wait in between which she normally does well. However at the fourth portion she is starting to grumble and by 5th and final portion she is aggressive. She can count... I feel quite stuck on how to help her.
