Puppies need to potty every 4 hours until they are 4 months old, at which time they can hold it for about 6 hours. They should be able to hold it for about 8 hours by the time they’re 6-7 months old. Puppies will need to potty approx. 5-30 minutes after eating or drinking, and always after a nap.
Keeping this in mind, the best way to train your puppy is by combining kennel training with doggie door training. Dogs have a natural denning instinct, so they will naturally make a kennel their bed, or den. Dogs will not potty in their bed, (unless there are extreme circumstances, such as being locked in there for too long) so by keeping your dog in a kennel when you are not home and then taking them directly outside when you let them out, they will learn where to go. If you are able to install a doggie door in a patio door, etc., the kennel can be bumped up against the doggie door when you are not home so your pup only has access to the outside and his bed. This is by far the fastest way to potty train. When you are home, your dog will always have access to the yard when he has to go, so there will be no accidents. If you do catch your puppy in the act of piddling in the house, say NO and take your puppy outside. When he piddles outside, praise him excessively and give him treats. He will then associate piddling outside with getting yummy food and love and will do it more often. DO NOT HIT YOUR PUPPY. This will only make him fear and dislike you, and will make him more prone to biting in the future. Positive reinforcement works the best with dogs. If your puppy leaves you a puddle or a pile and you find it after the act, don’t bother punishing the dog. He won’t remember why he’s bad, only that you’re mad and he has no idea why. The most effective training is watching your pup constantly when he is in the house so you can catch him before he goes.
Puppies explore and learn by chewing on things and digging in things. Give your pup chew toys in his kennel. By providing your pup with plenty of toys to chew on and by taking him to the park to dig in the sand, he will be less likely to dig in your yard and chew up your stuff. Keep all shoes, candles, etc. out of the reach of your pup or he WILL eat them. If you catch your pup chewing on something he shouldn’t, take it away, say NO, and replace the item with a proper chew toy. In time, your dog will learn what’s OK to chew.
Do not give your dog stuffed animals or stuffed quilts as the stuffing can choke your dog. Also, your pup can’t tell the difference between a stuffed toy and a stuffed couch cushion. that’s just asking for trouble!
Speaking from experience, though it can be so cute to watch a Dane puppy destroy a newspaper or a stuffed toy, you will regret allowing him to do this later. Bad habits are hard to break, and when that 175 pound dog decides to destroy all your household paper products or your couch cushions while you are asleep, it is not so amusing that next morning.
Be firm.
Allow him to play with TOYS ONLY!
