One of my pet peeves that I see in new dog owners (and keep in mind, I am no expert, more just a conscientious owner myself) is the lack of exercise after bringing a puppy home. People bring a pup home, and after the first few days of "cute" wear off, the pup starts to nip, bite, and even exhibit destructive behavior. The owner gets frustrated and either shouts, disciplines the dog, or worse! Often times this is how pups end up in rescues.
