...When these cute little puppies create a problem at home, many owners don't know what to do. It's important for any dog owner to train the pup as early as possible.  We need to understand that there are puppies who can easily grasp the training, while there are others who are left a bit behind. If you think your puppy falls into the second category, do not be discouraged. You need to persevere in order to successfully train your puppy. By applying the right techniques as well as the right attitude, your dog will learn to behave properly whether he's inside or outside the house.

It's important to take note that dogs are pack animals. They are territorial and they do not want anyone including people to invade their space. Aside from that, they follow the commands of their pack leader. Owners should assert themselves as the pack leader who is responsible for their food, hygiene and behavior. Consistency and fair leadership should be remembered because it's the key to successful training.

It is necessary for a puppy to have his own crate. This serves as his comfort zone, an area where he rest and sleep. Although some puppies pee or poop anywhere, they always keep their crate clean. Thus, owners should be able to provide a crate that the puppy will love to dwell on. Adding to that, putting the puppy to his crate should not be in a form of punishment whenever mistakes are committed. It will be a lot easier to put the puppy to his crate when he loves to be on it. So do not be cruel to your puppy rather; always impose authority in a good way.
When buying a crate for your puppy, always consider the size of it. It should accommodate your dog when he is fully grown and it should have dividers so that you are assured that your puppy will not pee or poop in his sleeping area. Always maintain the crate as an area where the puppy feels security and comfort.

Feeding the dog should be done on a schedule. You have to set the number of meals that he ought to consume every day and this should be done consistently. You can place his food near his crate together with his toys. Choose a wholesome food and ask recommendations from your veterinarian. It is important to let him consume healthy foods only and appropriate diet should be imposed all the time.  Steer away from table food, and unless you're an expert, don't try to make your own dog food!

As a pack leader and owner of the dog, it is necessary to determine the right place for him to pee. The backyard is the perfect place for the puppy to pee, but it should be accessible on his part.  To establish the puppy’s peeing routine, you need to consistently bring the puppy to that area. Know that puppies pee frequently and that they have low urine retention. They need to pee from 10 to 12 times per day so you have to bring him to that area at least every two hours. This means that it is your responsibility to wake up at the middle of the night to take the pup to his pee spot. Meanwhile, you also have to learn the puppy’s body language before he pees. There are some puppies that sniff, go round in circles, or stand with the rear leg up.

It is very helpful to train the puppy to poop whenever you command him to do so. You can make use of a phrase like “go poop” or whatever you prefer. Making a signal for this will enable the puppy to defecate at the right time and at the appropriate spot. Thus, the puppy will not create a mess inside or outside the house. When this is successfully done, make sure to cuddle the puppy and give him a food treat so that he associates the treat with the correct response to your command.

Mistakes usually happen the first few weeks of training.  Never punish the puppy, praise his appropriate behavior and immediately clean up the mess he created.  Use a cleaning product that will leave no odor or the puppy will return to that area.

Points to Remember in House Training your Puppy:

1. Select the best diet for your dog!
2. Food treats should be given when he properly executes your commands                                                                                                                     3. Praise your puppy when he does his toilet in the right place. Reinforcing his good behavior will encourage him to do it again.  Don't just turn your pup out alone in the backyard and expect him to know what he's out there for!
4. Be consistent with your commands.

When puppies exhibit a bad behavior, it needs to be corrected by scolding him verbally, not through physical harm. But dogs do not have the capacity to comprehend what you are saying, that's why it's important to catch the puppy in the act so that scolding will be effective.  (praising good behavior is better then scolding bad so try to avoid the bad behavior in the first place)
Dog owners need to have lots of patience while training, especially when it comes to housebreaking. The mess should be cleaned properly and thoroughly, and the dog should be trained to do it in your selected area. Be consistent with everything so that the dog will not be confused!
