Puppies do not guess where you want them to go; they follow their nose to wherever smells like the right place. A toilet-training spray works on exactly that instinct. A few pumps on a training pad, a patch of grass or the corner of the garden you have chosen gives your puppy a reason to head there rather than picking a spot of their own behind the sofa, which is the habit you then have to undo.

It is a scent cue, which means it works alongside a routine rather than instead of one. Take the puppy out after sleeping, after eating and after play, spray the target, wait, and praise the moment they finish rather than once they are back indoors. Reapply as the scent fades. On carpet or anything you care about, test a small hidden area first, which is sensible with any spray however gentle the formula.
