How dogs think & learn

Puppies arrive blind and deaf, then open up to the world in a rush. Between roughly three and twelve weeks they pass through a sensitive window when new sights, sounds and people are easily accepted. Adolescence, from around six months, can bring wobbly manners and new worries – that’s normal brain development, not defiance. Adult dogs settle, and seniors may slow down or need gentler routines. Matching your expectations to the stage makes training kinder and quicker.

Your dog’s nose holds hundreds of millions of scent receptors and a dedicated brain area for smell, so a short sniff tells them who passed, when, and how they felt. Hearing picks up higher pitches and quieter sounds than ours. Eyesight is tuned to movement and low light rather than fine detail or red tones. Remember this when training: a fascinating smell can genuinely outweigh your voice, and a moving hand is clearer than a still word.

Dogs learn in two big ways. They link events together – the lead comes out, so a walk is coming. And they repeat behaviours that pay off while dropping ones that don’t. That means every moment is a lesson, not just training sessions. If jumping up earns attention, jumping grows. If sitting earns attention, sitting grows. Your job is to make the behaviour you want the easiest and most rewarding choice.

Dogs feel joy, fear, frustration and contentment. A worried or overexcited dog can’t learn well, in the same way you’d struggle to do maths during a fire alarm. Before teaching anything, check your dog is calm enough to think: can they take a treat gently and respond to their name? If not, add distance, lower the excitement, or try again later. Trust grows when your dog learns that you keep them safe.
