The most critical window in a puppy's life runs from around four to sixteen weeks, this is when the most rapid learning happens, and when experiences have the greatest lasting impact on future social behaviour. Puppies are naturally curious and playful during this stage, which makes it the ideal time to start teaching commands and shaping good habits. Most vets recommend limiting a puppy's exposure to unknown dogs until their vaccination course finishes, typically around ten to twelve weeks, but the critical socialisation window doesn't pause to wait for that. Carrying your puppy outside, letting them watch the world from a secure bag, having visitors come to them at home, and controlled introductions to fully vaccinated adult dogs all let socialisation continue safely. Royvon offers residential puppy programmes at Surrey and Merthyr Tydfil venues, with daily training and activity sessions alongside enriching walks. Puppies learn calm house behaviour, basic obedience, and owners receive training guidance to continue at home. Puppy classes are open to puppies aged eleven to twenty-four weeks, designed to teach owners how to be their puppy's trainer, covering life skills, socialisation, recall, and lead walking.
