Socializing your dog exposes them to all kinds of sights sounds smells and weird objects. This teaches them that no matter what they encounter you will protect them and they don’t need to worry about it or feel the need to protect themselves. They will become used to these things and learn the world isn’t so big bad and scary 🙂 This creates a confident and well mannered dog in public. Lola’s first field trip was a bit daunting and this cart was quite unsettling at first. With a little calm energy and patient coaxing we convinced her that the cart was nothing to fear and could even be a fun ride 😉 Good Girl Lola!!! & Thanks for your help Chris!!!
