Start with a consistent schedule and designated spot

Small dogs learn fastest when you take them outside at the same times every day. Take your dog out first thing in the morning, after meals (usually 15 to 30 minutes later), after naps, before bedtime, and several times during the day—typically every 2 to 3 hours for puppies under 4 months old. The younger the dog, the more often you need to go out.

Choose one specific spot in your yard or on the street where you want your dog to go. Dogs naturally want to return to places where they have already gone, so using the same spot builds the habit faster. Take your dog on a leash to that spot, wait quietly for 5 to 10 minutes, and praise heavily the moment they go. If nothing happens after 10 minutes, go back inside and try again in 30 minutes.

Small dogs have smaller bladders than large breeds, so they genuinely cannot hold it as long. A general rule: a puppy can hold their bladder for about one hour per month of age, plus one. A 3-month-old puppy can typically hold it for about 4 hours. Adult small dogs usually need to go out 4 to 6 times daily, though some do well with 3 times if they are older and well-trained.

Key Takeaways

  • Take your small dog outside on a fixed schedule—first thing in the morning, after meals, after naps, and before bed—because consistency is the foundation of potty training.
  • Use the same outdoor spot every time so your dog's natural instinct to return to familiar places reinforces the habit.
  • Praise and reward when ready when your dog goes in the right place, because small dogs respond well to positive reinforcement and will repeat behavior that gets attention.
  • Confine your dog to a small space like a crate or pen when you cannot watch them, since dogs avoid soiling where they sleep and this prevents accidents that set back training.
  • Expect setbacks and never punish accidents, because fear and confusion slow down learning and can cause your dog to hide to go to the bathroom.

Watch for signals and reward the right behavior

Small dogs often show signs they need to go: sniffing the ground, circling, whining, scratching at the door, or sudden restlessness. Learn your individual dog's signals and respond when ready. The faster you get them outside after they signal, the more they learn that signaling gets results.

When your dog goes outside in the right spot, reward within seconds. Use high-value treats (small pieces of chicken, cheese, or commercial training treats), enthusiastic praise, or a favorite toy. The reward must come when ready—within 2 to 3 seconds—so your dog connects the reward to the act of going outside, not to coming back inside or something else that happened after.

Small dogs are food-motivated, so treats work especially well. Use treats they do not get any other time, so going outside remains special. After your dog has been accident-free for several weeks, you can gradually reduce treat rewards and rely more on praise, but keep rewarding occasionally so the behavior stays strong.

Confine your dog when you cannot supervise

A crate, pen, or small room is your most powerful training tool. Dogs naturally avoid soiling where they sleep, so confinement teaches bladder control. When you cannot watch your dog—while you are at work, sleeping, or busy—put them in a space just large enough to stand, turn around, and lie down. Too large a space and they will go in one corner and sleep in another.

A crate should be just big enough for your dog to stretch out. If you buy one for a growing puppy, use a divider to make the space smaller now and adjust it as they grow. Small dogs do well in crates 18 to 24 inches long. Never use the crate as punishment, and never leave your dog crated for longer than they can hold their bladder—usually 4 to 6 hours for adult small dogs, less for puppies.

When you let your dog out of the crate, take them directly outside to their designated spot. This teaches them that crate time leads to outdoor time, which leads to the chance to go. If they go outside, reward. If they do not, bring them back in and crate them again for 30 minutes, then try outside once more.

Handle accidents without punishment

Accidents will happen, especially with puppies and newly adopted dogs. Never punish your dog for going inside—not with yelling, hitting, rubbing their nose in it, or any form of fear-based correction. Punishment teaches your dog to fear you and to hide when they need to go, which makes training much harder and can create long-term anxiety.

If you catch your dog in the act, calmly interrupt them (a straightforward "outside" works), take them to their spot, and reward if they finish there. If you find an accident after the fact, straightforward clean it up thoroughly with an enzymatic cleaner (one made for pet urine) and move on. Your dog cannot connect a punishment to something that happened hours ago.

Enzymatic cleaners are important because regular cleaners do not fully remove the scent. If your dog can still smell urine in a spot, they are more likely to go there again. Brands like Nature's Miracle and Rocco & Roxie are designed to break down urine at the molecular level.

Manage diet and water to prevent accidents

What goes in on a schedule comes out on a schedule. Feed your small dog at the same times each day—usually twice daily for adults, three times for puppies under 6 months. Feed in the morning, at midday if needed, and in the evening. Take your dog outside 15 to 30 minutes after eating.

Water access matters too. Puppies and young dogs should have water available most of the time, but you can remove the water bowl 2 to 3 hours before bedtime to reduce nighttime accidents. Adult dogs can usually have water available all day. If your dog drinks a lot more than usual, talk to a veterinarian—excessive thirst can signal a health issue.

Avoid feeding table scraps and treats that are high in salt or fat, because they can upset digestion and make accidents more likely. Stick to a consistent, high-quality dog food and limit treats to training rewards.

Expect a longer timeline for adult rescues and older dogs

Puppies can be housetrained in 4 to 6 months with consistent effort, though some take longer. Adult dogs and rescues may take 8 weeks to several months because they may have learned bad habits, lived in conditions where they had no choice but to go inside, or straightforward need time to adjust to a new home and routine.

An adult dog is not broken if they have accidents in the first weeks. They are learning a new environment, a new schedule, and a new set of rules. Stick to the same schedule, use the same spot, reward heavily, and be patient. Most adult dogs housetrain faster than puppies once they understand the routine, because they have better bladder control.

If your adult dog was previously housetrained and suddenly has accidents, see a veterinarian. Sudden changes in bathroom habits can signal a urinary tract infection, diabetes, or other medical issues that need treatment.

Troubleshoot common setbacks

Nighttime accidents: Puppies under 4 to 6 months usually cannot hold their bladder all night. Use a crate at night and take your puppy out once during the night if needed. As they grow, gradually extend the time between nighttime trips. Adult small dogs often housetrain during the day before they housetrain at night. If your adult dog still has nighttime accidents after months of daytime success, talk to your vet—it may be a medical issue or straightforward a sign they need one more outdoor trip before bed.

Going in the crate: If your dog goes in the crate, the space is too large, they are spending too much time crated, or they are anxious about the crate itself. Make the space smaller with a divider, reduce crate time, and make the crate a positive place by feeding meals inside and leaving the door open when you are home. Never force your dog into the crate or use it as punishment.

Refusing to go outside: Some small dogs are scared of weather, loud noises, or unfamiliar outdoor spaces. Start with short trips to a quiet spot. Use high-value treats and praise. If your dog is fearful, go at quieter times of day. Never force them; let them warm up to the outdoor space at their own pace.

Going in one spot indoors repeatedly: Clean that spot with an enzymatic cleaner. If it is a carpet, you may need to remove and replace the section or use a blacklight to find all spots and treat them. Consider blocking access to that area while training is underway.

Frequently Asked Questions

How old should my puppy be before I start potty training?

You can start as soon as you bring your puppy home, even at 8 weeks old. Puppies under 12 weeks have very limited bladder control, so expect frequent accidents. The goal at this age is to establish the routine and reward going outside, not to achieve perfection. Most puppies are reliably housetrained by 4 to 6 months, though some take longer.

Can I use puppy pads instead of taking my dog outside?

Puppy pads teach your dog that going inside the house is acceptable, which can confuse training. If you must use them because you cannot get outside frequently, place them near the door and gradually move them closer to the exit over weeks. The goal is to transition to outdoor-only going. Most trainers recommend skipping pads and going straight to outdoor training if your schedule allows.

What if my small dog marks territory indoors?

Marking (small amounts of urine on furniture, walls, or other dogs) is different from full potty accidents. Marking is often a behavioral or anxiety issue rather than a housetrain issue. Spaying or neutering usually reduces marking significantly. In the meantime, use enzymatic cleaner on marked spots and consider consulting a trainer or veterinarian if marking is frequent.

How do I know if my dog's accidents are a medical problem?

If your previously housetrained dog suddenly has frequent accidents, strains to go, goes more often than usual, or has diarrhea or blood in their urine, see a veterinarian. Urinary tract infections, incontinence, and digestive issues are common in small dogs and are treatable. Do not assume it is a training failure until your vet rules out medical causes.

Is it ever too late to housetrain a dog?

No. Dogs of any age can learn, though older dogs with years of indoor habits may take longer. Stick to the same schedule, use the same spot, reward heavily, and be patient. An adult dog housetrained for the first time may take 8 weeks to several months, but most do learn with consistency.
