Combining two popular titles in one value-priced edition, Before and After Getting Your Puppy is a simple, practical guide for anyone bringing a new puppy into the home. In clear steps, with helpful photos and easy-to-follow training deadlines, Dr. Ian Dunbar, who pioneered puppy classes and a loving style of dog training in the 1970s, presents a structured yet playful and humorous plan for raising a wonderful dog. The guide is based on six developmental deadlines: completing owner education and preparation, assessing a puppy's prior socialization and education, teaching errorless house-training and chewtoy-training, completing a socialization program of meeting strange dogs and people, learning bite inhibition, and continuing a program of ongoing training. In the first half of the book, Dr. Dunbar focuses on what the owner needs to know to select a great puppy. In the second half, he presents the crucial lessons the puppy must be taught during its impressionable early development - using a kind, positive approach that, over time, has been proven the most effective.
