Sadly, many dogs are surrendered to animal shelters due to housetraining problems, and about 25% of behavior-related visits to veterinarians involve the same issue. One of the main reasons housetraining fails is because dog parents tend to view their canine family members as furry humans. They react to pet accidents on the floor the same way they would react if a person left the mess. While it's true that dogs are members of the family, they aren't human, and when potty mistakes in the house are mishandled, very often the result is the opposite of what was desired, and a bad situation gets worse.

Elimination is a natural function, and new puppies in particular can be expected to relieve themselves whenever and wherever the urge strikes until they are both old enough to control the urge physiologically, and appropriately motivated to pee and poop outdoors. Both factors must be in play before puppies can be successfully housetrained.
The good news is that it's entirely possible to successfully housetrain a dog at any age. Teaching good potty habits to a puppy is much easier than training or re-training an adult dog, but it's far from impossible. There are three things that will improve the likelihood of success in housetraining your dog. They are consistency, positive reinforcement, and patience.

The optimal time to begin housetraining your puppy is the day she or he comes home. However, it's important to remember that like human infants, younger puppies don't have the neurological development necessary to regulate elimination. They aren't yet able to control their bladder or hold urine in.

The first step is to find an outdoor grassy space you can consistently take your puppy to when it's potty time. His brain is developed enough at about 8.5 weeks to begin to associate the smell and surface of his potty spot and the act of elimination. Not only can most puppies at 8.5 weeks start to make these important mental connections, but they are also better able to control when and where they relieve themselves. Housetraining your puppy is a two-phase process. First, he must learn to relieve himself in the designated spot, and then he must learn to hold his urine and feces until he's in that spot.

A young puppy needs to be taken to his potty spot about every hour, and always after eating, playing, and sleeping. It's also important to watch his behavior and learn his "I gotta go" signals. The older he gets, the less often he'll need to go. But no dog should be expected to last 8 or 10 hours without a potty break, especially a puppy.

Housetraining Ground Rules
1. Never leave your un-housetrained dog unattended, not even for a minute — If you aren't actively engaged with your dog, having her in the same room with you doesn't count. It's very important not to give her opportunities to fail at housetraining. When you can't engage with your dog, which of course isn't possible every minute of every day, she should be in her crate. Some pet parents believe crates are bad or negative, but honestly, nothing could be further from the truth. A crate is a very natural, normal habitat for a dog, providing your pup doesn't associate it with punishment. You should never put your dog in a crate as punishment.

Dogs are den dwellers by nature. Under normal circumstances, they enjoy and seek out small, safe, warm spaces in which to rest. If you provide your pup with her own little den in the form of a crate, and there's nothing forceful or punishing about her association with it, she'll learn to love it.

Nature has arranged it such that a small, enclosed area will help your puppy learn conscious control of her urge to eliminate. In the wild, mother wolves teach their litters to potty outside the den. If you provide your puppy with her own den, you're working in harmony with her natural desire not to soil it. Other uses for a crate include keeping your pet safe from a long list of dangers and potential disasters — everything from electrical cords to the cat's food bowl to houseguests with small children.

If you're dead set against crate-training your un-housetrained dog, then your only other option is to tether her to you so no matter where you go, she's right there beside you. The way to do this is to put a clip on a short leash (no longer than 4 feet), put the leash on your dog, and clip it to your clothing or belt. Obviously, this arrangement wouldn't be practical for many of you, which is why I recommend embracing the use of a crate.

2. Feed your dog on a schedule — If you always leave a bowl of food available for your un-housetrained dog to nibble at, he'll nibble all day and he'll need to poop at entirely unpredictable times. It will be just about impossible to figure out the best time to take him outside to relieve himself. I don't recommend the all-day-buffet method of feeding pets under any circumstances, but it's an especially bad idea with a dog that isn't housetrained. If you're feeding your dog or puppy on a consistent once-, twice- or three-times-a-day schedule (depending on his age), you know that within 30 minutes to an hour after eating, he'll need to go potty. It's important that someone in the household is ready and willing at those times to take the dog out.

3. Reward your dog for good behavior — In order to successfully potty train your dog, it's crucial that you reward for good behavior, and praise her in ways she understands. Timing is also very important here. Your dog will pick up cues from the tone of your voice. If you're saying things like "Good girl," "That's what I'm looking for," "Nice job," in a quiet, loving, calm tone immediately after she goes, you're reinforcing that behavior.

Almost all dogs speak the language of food, so treats are also a good reward during the housetraining process. When your dog eliminates in the right spot outside, praise her with words and give her a treat within 1 to 3 seconds of the behavior. Remember that consistency is crucial, so make sure you have treats with you to reward her within 3 seconds every time she goes in the right spot. Food rewards are typically only necessary for a short time before both puppies and adult dogs respond to praise alone. Once your dog is fully housetrained, you can completely eliminate the need for treats if you wish, and offer just verbal praise instead.

4. Don't punish your dog for mistakes — No shouting, absolutely no physical contact, and never, ever rub your dog's nose in his mess. For many people, this can be the most difficult rule to follow, but I can't stress enough how important it is.

Of course, it's frustrating when your four-legged family member just doesn't seem to want to get with the program. But to successfully housetrain your pup, you must avoid punishing any type of mistake. And mistakes are going to happen. It's important to adjust your attitude toward your dog when it comes to house­training mistakes. First, don't give him a chance to fail. But when he does, recognize that your response sets the stage for everything that happens after. If you respond negatively, you teach your puppy to fear you. There's a good chance he'll respond in the future by going into another room out of your line of sight to potty, rather than learning to trust you and tell you when he needs to go outside.

Even if you catch your pup in the act of relieving himself indoors, make sure you don't respond with anger or force. What can happen in that case is he'll connect you seeing him eliminate with your anger, and he may get sneaky about it. It's important that every situation pertaining to housetraining is very positive. In short, you can't punish or frighten a dog into appropriate behavior. The important thing to remember is by the time your dog is relieving himself on your floor, your opportunity for a successful potty break outside has passed. Ensuring you're doing your part in helping your dog succeed is the most vital aspect of housetraining.
