Top 10 Most Aggressive Dog Breeds of 2023

Part of being human is experiencing a broad range of emotions; from love to hate, and sadness to anger. While this broad range of emotions is expected from humans, we aren't the only living things that can experience them. Countless species, including dogs display and experience a broad range of emotions throughout their lives.

While they are known for being man's best friend, dogs can also be loving, affectionate, caring, and protective; just as they can be scared, angry, and aggressive.
