Puppies are capable of learning simple commands from a very young age but don’t try to give your puppy a meaningful training session if he is tired, highly excited or busy exploring. You need his full attention, otherwise you’re wasting your time. You can build up to training sessions in more distracting environments once your puppy is reliably responding to your commands at home.
Many owners appear disappointed that their young puppy will not toilet when out on a walk, yet relieves itself the second it gets back home. This is because the puppy has been taught to toilet only at home (hopefully in its garden), and being creatures of habit, they often wait until they have returned home before evacuating their bladder and/ or bowels.
