Many common behavior problems of older puppies (over 6 months) and adult dogs are caused by separation anxiety, lack of feeling secure when left alone. Crates can be very helpful or very harmful in solving these problems. Crates must be introduced gradually , making every association with the crate as positive and pleasant as possible.
