If a previously house-trained adult dog starts peeing indoors, consider a medical cause before assuming a training problem. Contact your veterinarian, especially if the change is sudden or accompanied by more drinking, frequent attempts, pain, or leakage during sleep. Accidents are not evidence that your dachshund is being spiteful.
Repeated straining with little or no urine, significant pain, collapse, or a visibly unwell dog needs urgent veterinary attention. Do not wait for a training appointment when the dog may be unable to urinate.
Notice what kind of accident is happening
Large puddles, small amounts on upright objects, dribbling while asleep, and urination during an excited greeting are different patterns. They are useful observations, not diagnoses. More than one cause can be present at the same time.
Record when the dog last went outside, how much urine you noticed, and what was happening immediately beforehand. If possible, note whether normal urination also occurs outdoors.
Medical causes come first
Urinary discomfort, increased urine production, loss of bladder control, mobility problems, and other health changes can all contribute to house soiling. Older dogs may have several overlapping issues. Do not dismiss a new problem as an inevitable part of aging.
Your veterinarian may recommend urine testing and other investigations based on the examination. A urine culture helps investigate bacterial infection; it does not, by itself, diagnose every possible cause such as stones or tumors. Treatment depends on the findings, not on a general assumption that antibiotics or supplements will fix accidents.
Do not restrict drinking water to keep the floor dry unless your veterinarian gives specific instructions. Increased thirst is information the veterinary team needs.
Bathroom access may no longer be adequate
Review the practical route outside. Has the schedule changed? Is a door closed that used to be open? Is the dog reluctant to use slippery flooring, steps, cold ground, or a noisy yard? A dog may know where to toilet but struggle to reach it comfortably.
Offer more frequent opportunities while the cause is investigated. Accompany the dog, reward toileting in the intended place, and make the route easy to use. Arrange a visitor or walker if the interval between opportunities is too long for the dog.
Marking, excitement, and distress
Small amounts in particular locations may involve marking, but a medical problem still needs consideration. Urination during greetings may be associated with excitement or fear. Keep arrivals calm and avoid leaning over or crowding a worried dog.
If accidents occur during absences, use a camera when safe to see whether there are other signs of distress. Separation anxiety is one possibility, not the automatic explanation for every puddle found after work.
Clean without adding a new hazard
Use a pet-appropriate enzymatic cleaner according to the label and keep the dog away until the area is safe to use. Test the product on the surface first if needed. Avoid essential-oil repellents, strong improvised mixtures, or using a smell to frighten the dog away from an area.
Never mix cleaning products, and do not rub the dog's nose in urine or feces. Punishment can make the dog afraid to eliminate in front of you without teaching the desired location.
Help your veterinarian narrow it down
- When did the accidents begin?
- Has drinking, appetite, activity, or medication changed?
- Is the dog straining, licking the urinary area, or showing discomfort?
- Does leakage happen asleep or while walking?
- Are accidents linked to greetings, visitors, or absences?
- How often is the dog offered a comfortable toilet opportunity?
Ask whether the clinic wants a urine sample and how it should be collected. Do not delay an urgent visit to obtain one. Once health and access needs are addressed, a tailored training plan can deal with any remaining behavioral component.
