Appropriate socialization with other dogs during puppyhood shapes lifelong social behavior and reduces the risk of fear-based aggression.
Dog-dog socialization quality has profound lifelong welfare implications. Dogs who learn to communicate effectively with other dogs have more enriched social lives and fewer fear-based stress responses. Owners who prevent all dog interaction out of protectiveness, or force interactions that frighten their puppy, both compromise social development. Good socialization involves careful selection of calm, appropriate dog partners, attention to body language, and allowing puppies to approach and retreat on their own terms.
