A video from the YouTube channel @ThatGoldenMagic shows how quickly a dog can switch personality between mother and father, depending on who is the main focus. The video also highlights the importance of play fighting as an important enrichment activity for dogs, helping them socialize and communicate with each other. Play fighting can also enhance dog's confidence and control their own strength when it comes to playfighting. However, it is also important to ensure that your dog knows the right time and place to let out aggression.
