Bringing a new puppy into your home is a big commitment, so it's important not to take the decision lightly.
When you look at a litter or walk down the aisles of a shelter, look for a puppy that is actively seeking out your attention and does not seem overly shy or wary of you.
Some people are naturally drawn to pups that are gregarious and playful while others tend to go toward the shy or frightened pup.
Be aware, however, that the decision you make will impact your life in many different ways, so take your time. Pups that are shy may continue to exhibit shyness as they grow and this could develop into fear behavior as an adult that is hard to manage.
Spend time observing a puppy in her environement and watch how she interacts with other pups, adult dogs, and people around her.
