my 12 weeks old German Shepherd puppy gets really aggressive towards his father every time his dad gets excited. one thing I noticed is that every time I grab the leash to go for walks, my puppy will start biting and growling at his father. I know if this continues when he gets bigger they will probably fight. how can I avoid this behavior?
