Mike and his family enjoy having Otto, their yellow Labrador, around their home. But they sometimes encounter problems when the kids would play in the backyard with the dog. Otto would repeatedly knock them down and when Mike would join in to play with them the dog would try to mount on him. At times if Mike scolds at his children to reprimand them, Otto would get distressed and start growling. Mike tried spanking Otto or tapping him on his nose, but nothing seemed to be curbing Otto's aggression.



Unfortunately, Mike chose to give up on Otto's behavior. But at a dinner party, Mike found himself talking his frustration over Otto's aggressive behavior with a neighbor. His neighbor recommended a dog trainer. He was also told that the trainer would visit them in their house to work with Mike and his family to be part of the crucial training for aggressive dogs like Otto.

The trainer paid a surprise visit to Mike's house to observe and gather information regarding Otto's behavior. As Mike and the kids huddled and played together, the trainer immediately noticed Otto's behavior and how he acts upon the situation. The trainer talked to Mike and suggested that the family stop allowing Otto to assert that he was the Alpha Dog, and that Mike would need to establish himself as the leader of Otto's pack. The trainer further explained that dog's have a pack mentality wherein one dog has dominance over everyone. Otto's behavior was a way of him presenting he was in charge.

Bruce followed the trainer's advice and started taking control over everything. The trainer explained to Bruce that Matt should wait first for permission to use any toy or even to eat. Matt needs to acknowledge that Bruce and his family were in control. Bruce put up Matt's toys and refrain form letting him to jump up on the couch or bed unless he sat first.

When Matt would want to play or go out, Bruce began training him to sit in front of the toy box or doorway. For when he sat on command, Bruce would let him play with a toy or open the door for him. If Matt would not follow, Bruce would not give Matt what he wanted. Bruce also instructed his kids how to do the same thing. At first Matt would not respond, but realized that he was not getting what he wanted, so he would follow to commands.

The trainer also discouraged Mike from playing tug-of-war with Otto. Even though this was one of Mike's favorite games to play with Otto, he observed that Otto's behavior worsened after a game of tug-of-war. The trainer cited that these kinds of games are instinctual ways for dogs to assert dominance in the pack. He suggested games of fetch and using other active toys to excite Otto.

Months have passed and Matt's aggression dissipated. Every now and then, Matt would try to reassert himself as the alpha dog, but the family now knows not to give in to Matt's demands. Matt had improved and no longer knocks down the kids when they would play, and he definitely stopped mounting Bruce. Bruce was now able to even teach him other tricks that he never thought Matt was capable of.

The key to Gab's success with Teru was that the family had to establish dominance over Teru. After Teru realized his spot in the hierarchy, he was better-behaved and the aggression subsided.
