Realize my 2 boys also have this problem but after sometime, with constant
talking and telling them not to, it went away.
Cesar Milan's methods are for red zone dogs, please dont use it on our own dogs.
really too confident already, need to really understand dog over period of time to handle or rehabilitate them and also always on the guard for dog with biting/aggressive behaviour problem when interact close to them. any small movement may make them defensive, bite 1st then think or confirm its safe for them.
I have been bitten so many times till I learned the hard way to be more careful, assess situation as proper as possible and on guard.
human beings with so much intelligent can sometime behave so abnormal or act out of the way so for them being animal, unpredictable behaviour is likely especially those with behaviour issue.
that being said, dog who trust you will avoid biting you even in the mist of chaos. I broke off some fight between dogs from time to time with hands, those that recognise I am good to them will avoid biting my hands when I physically in contact with them during fight. if they accidentally bitten me, the bit will be mild and let go immediately. however if the dog is those panicky or new to you they have high chance of biting you during chaos situation, approach them with care.
remember rehabilitation takes time and need proper assessment by trained expert to determine proper & correct approach and have lots of patience else objectives may not met or resulted worse than before.
so please dont read some book or watch tv and try on your own, these material may be incomplete or application details are vague thus for references only.
