We have a new addition -2 year old who has spent most of her life in a kennel or crated at the trainers. Therefore her genuine house training is not refined. In 3 weeks she has chewed computer cables, reading glasses, stairs,chairs etc. she is a great dog otherwise????... how do we break this bad behavior.. many times the damage is already done when we find it.... therefore it is hard to scold after the fact...SHE ACTS LIKE A PUPPY... is it that she never had the proper training as a pup. She gets a ton of exercise with our 15 month male. Any ideas how to cure this problem... short of giving her back to the trainer.
