One of the first things owners teach their puppy is not to eliminate in the house.  One very effective method – one uses by most breeders and trainers – is crate training.  Not only can you housetrain a puppy using a crate but, when used correctly, the dog naturally learns to look upon the crate as his den.  He will seed out the crate when he wishes to rest undisturbed. 

                The crate’s success as a housetraining tool is simple:  Puppies will not soil their sleeping area if they can possibly avoid it.  But remember, that a puppy needs time to play.  Use the crate when you can’t watch the puppy but don’t overuse it.

                Crate training basics: Crates come in many different styles and sizes.  Choose one that will be large enough for an adult dog of your puppy’s breed to lay down, stand up, and turn around in without difficulty. 

                Many breeders use fiberglass or molded-plastic airline kennels as crates.  Avoid crates held together with zinc nuts and bolts as they can be poisonous should the dog swallow them.  Wire crates work well -  they fold up and are fairly portable.

                Put the crate in a location close to other family members to lessen the puppy’s anxieties.  Move it from kitchen or family room to the bedroom at night so your puppy will always feel a part of his new family. 

                Remove the puppy’s collar before he goes into his crate.  Then be prepared for his first experience with crate training – he will probably cry or whine.  Offer him a treat and close the door.  Leave the room but remain nearby.  At the first sigh of a separation response, such as barking or howling, intervene with a sharp, “NO!”  Your puppy should associate the reprimand with his actions and stop.  It may take four or five tries, but he will eventually settle down. 

                Once he is quiet, keep him in his crate for 30 to 45 minutes.  If he begins to cry, take him outside to relieve himself.  When he has accomplished that, praise him, take him back inside and allow him free time outside his crate.  If he starts chewing on something other than his toys, respond with a sharp “NO,” take the object away and replace it with a toy. 

                After 15 to 20 minutes of free time to play, put him back in his crate for a nap.  If he cries, correct him.  Because he is learning through association, consistency should help your puppy accept being in his crate after only a few tries.  When your puppy has been quiet for an hour or so, repeat the process.

                Be aware that your puppy will need to eliminate directly upon waking and shortly after eating or playing.  Also, a very young puppy will not be able to hold his urine all night, so be prepared to take him out at some point during the night to relieve himself.

                Put your puppy on his leash immediately after letting him out of the crate.  Rush him to the door, or carry him if he is small, to avoid an accident.  Be sure he relieves himself once he is outside. 

                Never place newspapers on the bottom of his crate, as these will only encourage him to eliminate there.  After you are sure your puppy isn’t wetting his bed, y can give him a towel or blanket, though he may be more comfortable without one.  Gradually lengthen the amount of time your puppy is llowed to play.  By the time he is five or six months old, he should be able to control himself for an hour or so between trips outside.

Saving your furniture:  The crate is also useful as an aid in curbing destructive behavior such as uncontrolled chewing.  As your puppy matures and proves himself capable of being loose in the house, give him that privilege.  The crate itself cannot stop your puppy’s need to chew when he is teething.  It is important to provide him with safe, chewable toys and nylon or rawhide bones or Kong chew toys.  If he continues to chew beyond the teething stage ( about 8 months), he is probably just bored so spend more time with him.  By the time he is 8 months old (a bit older for giant breeds), he should be able to walk around the house for most of the day once he has been allowed to relieve himself.  By 1 year of age, he should be mature enough to be trusted all night in the house, but keep his crate set up with the door open anyway.  Your dog will have become attached to his own private “den” and will look for it and may prefer to sleep there.
