Many widely held beliefs about dogs focus on genetics or training alone, but early experiences matter greatly, too! A 2025 study surveying over 4,000 dog owners found that adverse experiences in a dog’s first six months of life, such as abuse or relinquishment, were significantly associated with higher fear and aggression scores in adulthood when compared to dogs without early adversity. Breed ancestry also strongly influenced how dogs responded to adversity.
