There are many common issues that owners find problematic with their puppy's or kitten's behavior, such as eliminating in inappropriate locations, chewing, mouthing, growling, and biting. Many of these issues can be prevented or managed by helping owners understand normal canine and feline behavior and by teaching the puppy and kitten socially acceptable behaviors. The focus always should be on rewarding acceptable behaviors rather than punishing unacceptable ones. Puppy Preschool and Kitten Kindergarten classes are an ideal avenue to introduce pet owners to modern, humane ways to train and socialize their pets to be a valuable part of today's society.
