How does crate training work?
Like babies, puppies cannot control their bladders until they mature (usually between 3 and 6 months). Dogs have a natural instinct to avoid eliminating in their dens. Therefore, confining your puppy in his crate for the proper amount of time encourages him to “hold it” until you take him outside for a walk.
