Once your puppy has learned to accept the lead and doesn’t become agitated or stressed when it is put on, it’s time to venture outside. Again, keep in mind that this will be a new experience for your puppy. There will be lots of new sights, sounds and smells. If your puppy seems overwhelmed or over-stimulated at first, don’t worry, this is normal given the circumstances. Over time they will become used to the experience as it becomes a new part of their routine.
