Dogs have a sense of smell at least 10,000 times stronger than humans so ensure your puppy can move away from a new smell. These scents are a great, safe way to introduce new and unusual smells to their world:Herbs.Spices.Perfume / aftershaves used by people in your household (do not spray puppy with this, simply spray onto a cloth or napkin).Grass (if you don’t have a garden then bag some up and bring it to your pup).Bedding of other pets in the home.Hide food/treats under empty yoghurt pot or similar.Hide food around the house / garden and encourage puppy to sniff it out.
