Puppy Potty Training Regression: What to Do

A puppy who has gone weeks without an accident has built a habit, but that habit is still fragile. Several things can disrupt it. Many owners give their puppy more freedom around the house as soon as things go well, and a puppy who has the run of the house has more chances to sneak off and have an accident. Others reduce the frequency of trips, because the puppy seems reliable, or stop rewarding outdoor success.

Developmental changes play a part too. Adolescent puppies are more distractible, more independent, and more likely to forget their training in the excitement of exploring. Changes in routine, such as a new schedule, a move, a new family member, or travel, can also disrupt a young dog's habits. Stress, teething, and growth spurts can all add to it.

Before assuming it is a training issue, consider health. A sudden return of accidents after a long period of reliability is a good reason to see your vet. Several conditions can cause more frequent urination or reduced control.

• Urinary tract infections, which cause urgency, straining, or frequent small amounts.
• Bladder stones or crystals.
• Intestinal parasites or digestive upset, affecting bowel control.
• Diabetes or kidney problems, which increase thirst and urination, although they are less common in young puppies.
• Pain or discomfort, which may make a puppy reluctant to go outside.
• Dietary changes that affect the stomach.

Note: Take a urine or stool sample to your vet if you can, and describe the pattern of accidents. If your puppy strains, passes blood, or seems unwell, call your vet promptly.

If your vet gives the all-clear, treat regression as a signal to go back a step. Return to the schedule you used when your puppy was younger, with more frequent trips, and supervise closely. This is not a punishment, it is a refresher, and most puppies get back on track within a week or two.

1. Take your puppy out after waking, eating, playing, and napping, and every one to two hours in between.
2. Go with them, and reward immediately after they go in the right place.
3. Supervise indoors, using a leash, a pen, or a crate when you cannot watch.
4. Restrict access to the house to the rooms you can supervise.
5. Keep meal times and water on a regular schedule.
6. Gradually increase freedom again, once the puppy has gone a couple of weeks without accidents.

Accidents leave scent markers that attract your puppy back to the same spot. Regular household cleaners often do not remove them, and some, such as those containing ammonia, can smell like urine. Use an enzymatic cleaner designed to break down the odor, and follow the directions. Blot, do not scrub, and let it air dry.

Block access to areas where accidents happen frequently, and consider moving a rug or furniture for a while. A clean house helps your puppy choose the right place next time.

It is easy to react with frustration, but some responses make things worse. Avoid these.

• Scolding or punishing the puppy after the fact, which teaches them to hide when they go.
• Rubbing their nose in the accident, which is cruel and ineffective.
• Assuming they know better, and leaving them unsupervised.
• Skipping rewards for success, because it is now expected.
• Changing too many things at once, such as food, schedule, and location.
• Giving up on outdoor trips and switching to pads without a plan.

Adolescent dogs may mark indoors, particularly unneutered males, and this is different from house-training failures. Marking involves small amounts of urine, often on vertical surfaces. Discuss options with your vet, and manage the environment while you work on training.

Small breeds are famously slower to house-train, because of their small bladders and a tendency to be carried or left alone. Be patient, increase frequency, and use the same rules as for larger dogs. If your puppy has just been spayed or neutered, discomfort and medication can cause temporary changes, so ask your vet if accidents continue.
