My little Boxer German Sheperd crozz puppy who is about 2 and a bit months old is out of control. She is walked every day and jogs or runs with my boyfriend almost every night. When we walk around the house she grabs onto our pants and will not let go. She barks and growls at us alot and she digs in her water bowl sending water flying everywhere and covering the whole kitchen in dog water.. Is this normal for this breed of dog? Whats the best way to stop her?
