The other day we took Nova to Hobby Lobby with us, let her sniff around, meet some people, see sliding doors, grocery carts, etc. (of course we asked the employees if it was alright first, and brought a bag with cleaning supplies in case of a mess). It is so important for puppies to get exposure to different places, sights, sounds, and people. All in appropriate doses! Short car rides (Nova gets carsick easily so we've worked slowly with that so she doesn't attach anxiety to riding in the car, ginger capsules help with the nausea), short trips to stores that accept dogs, visiting friends and family, different trails, beaches, parks, and meeting dogs that are friendly to puppies. It's also crucial that highly dog-trafficked areas are avoided until vaccinations are completed.
