Aggressive 5 year old Jack
My Jack has recently developed an aggressive behavior, I ended a relationship and My self and my 5 year old Jack (Tonka) moved. Sense the move Tonka has attacked any one he does not know that enters MY home, I don't even know where to start to change this behavior Tonka is a very dominate Jack he runs our house and as he gets older i have realized i do not want to live this way with him.
If i discipline him he will Pee on me or in the house deliberately to show that he is the boss.
he had also developed the behavior to scratch his ear till it bleeds to get attention.
I have realized that Tonka is spoiled and that i am the problem as him and i grow together i see how much work he is and the troubles we are having are only getting worse by the day, if i do not correct this aggressive behavior im worried i will have to put him down :(
How do i become the pack leader to take control of this situation so Tonka and i can live together peacefully?
