The socialisation period in puppies (approximately 3-14 weeks) is critical for lifelong behavioural welfare, yet many puppies miss optimal socialisation due to early isolation or inappropriate experiences.
Puppy socialisation welfare is shaped by both what puppies experience and the quality of those experiences. Exposure alone is not enough - positive, controlled exposure with careful monitoring of puppy stress responses is required. Puppy classes, home visits, and planned socialisation programmes are valuable. The worst welfare outcomes arise from complete isolation during the critical period (as seen in some puppy farm contexts) or from traumatic exposure that creates lasting fear. Responsible breeding and early puppy care is a primary welfare intervention with lifelong consequences.
