Early socialisation is one of the most important determinants of lifelong companion dog welfare.
Dogs that miss adequate socialisation in the critical window live with chronic anxiety and fear that no amount of later training can fully reverse. Fear-based aggression, noise phobia, and generalised anxiety are the consequences of inadequate early experience. These conditions cause daily suffering and frequently result in relinquishment. Breeder and puppy buyer education about socialisation is a major welfare intervention.
