9 Reasons Dog Leaves Odorless Wet Spot, And What Should You Do?

It’s not unusual for dog owners to detect odorless wet spots throughout the house. Although determining the actual origin of the condition might be difficult, you should explore several possible reasons and solutions. First, it might indicate Urinary Incontinence if your dog is producing odorless wet spots.

Urine leakage is an inadvertent peeing that differs from deliberate urination or even urinating while enthusiastic, scared, or afraid. It is more common in older dogs, but it may also be an indication that your dog has a condition that needs veterinarian treatment and must not be overlooked.

It’s critical to understand urinary incontinence indications and when to seek medical care if the problem persists.

This article will go through these reasons and solutions so you can figure out why your dog is leaving odorless wet patches all over the home!

What are These Spots?

What are These Spots?

We may sometimes discover that our dog leaves wet spots around the home. However, they might be difficult to comprehend because they are odorless and arrive out of nowhere. This might indicate that your dog has Urinary Incontinence, which means it doesn’t always have total control over its bladder. This issue might also lead them to lose control of their bowels, producing both difficulties simultaneously!

It will almost certainly strike without notice when this occurs and will typically only last a short time until your dog feels better. Because dogs do not usually urinate or defecate wherever they sleep, this is referred to as “submissive urine.”

Reasons for Urinary Incontinence in Dogs

Reasons for Urinary Incontinence in Dogs

Incontinence in pets can happen for many reasons, including anomalies in bladder-controlling areas of the brain and spine, birth defects, and sickness. Because the muscles that keep urine in the bladder get weak with age, dogs may become incontinent. Following are some common reasons for this condition in dogs:

1. Dysfunction of The Bladder

Dysfunction of The Bladder

Bladder storage dysfunction is the inability of a dog’s bladder to store urine, which can happen for various causes. As a result, when the dog tries to urinate or defecate, it cannot relax the bladder and pelvic muscles. This can even happen after a dog’s urethra has been surgically repaired, resulting in persistent leaking.

Other disorders that induce fluid retention inside the dog’s bladder, such as diabetes, neurological difficulties, renal disease, or tumors in the urinary system, can also cause bladder storage failure.

2. UTIs

Urinary tract infections are another probable cause of odorless wet patches in dogs. Toxins in the urine can cause the urethra of a dog to become inflamed and irritated, resulting in UTIs. These toxins irritate your dog’s bladder, causing them to pee more frequently or deposit small volumes of urine all around your house.

Other signs include:

  • Frequent visits to the dog bathroom.
  • Urinating with difficulty.
  • Having blood in their urine.

Several environmental factors might influence how often your dog has to go outdoors to urinate.

3. Tumors

Bladder tumors can create odorless wet patches in dogs, especially in males. These tumors are usually benign and develop in dogs’ bladder tissue or urethra. The dog will not show any indication of the tumor until it develops massive enough to aggravate and inflame it. However, if your dog is always leaving odorless wet spots about the home, it might indicate bladder cancer.

Bladder tumors are most prevalent in older dogs between the ages of eight and ten or in female dogs that have experienced early menopause (six to seven years).

4. Brain Disorders

Brain Disorders

Dogs with brain disorders may also leave odorless wet spots. For example, Canine Cognitive Dysfunction Syndrome (CDS) and Dementia might impact a dog’s capacity to retain urine or defecate in the same way as they affect them intellectually.

If your dog loses control of his bladder muscles due to a brain condition that affects these mind-controlled systems of his body, he may start having accidents all over your house.

When a dog’s brain condition impairs his capacity to control feces and urine, the dog may start to experience mishaps in your home because his bladder muscles are no longer controllable.

Because of how this condition affects them psychologically, they may have problems recognizing you, staying still for a long time, or easily being distracted by everything around them.

5. Joint Discomfort

Your dog may have difficulty getting up after lying in bed or standing for longer durations if they have arthritis. If your dog’s arthritis is severe enough, they may begin to leave wet stains throughout the home because they can’t get up to go out.

Dogs with arthritis create odorless wet spots in a variety of ways. For example, this might occur when the dog has difficulty owing to joint discomfort. Other symptoms, such as trouble walking during the day or struggling to move after resting or taking a nap for an extended period, might develop if you notice them without warning.

6. Issues With the Spine

One of the most common canine health problems resulting in wet dog patches is spinal problems. This occurs when a dog’s bladder nerve reflexes are impaired, and/or a dog with spinal difficulties cannot control their urine flow, causing them to leave several odorless wet patches on their beds or throughout your home.

Age, overbreeding, and injury-related trauma, such as car accidents or falling from great heights, are all common causes of spinal issues. It can also be caused by congenital anomalies, such as spinal deformities in dogs.

Incontinence, lack of bowel control, and greater susceptibility to infections are possible side effects of spinal problems in dogs, culminating in a dog’s wet spot with an odor or even blood.

7. Gastrointestinal Problems

Gastrointestinal disorders can make it difficult for dogs to regulate their bladder muscles, resulting in odorless or bloody accidents at home. Diarrhea might also result in wet dog patches outside your home.

Symptoms of Gastrointestinal Disorder in dogs include nausea, vomiting, diarrhea, and other signs such as losing weight despite the increasing appetite for food. Taking your dog to the vet might help figure out what causes this and begin treatment for the same.

8. Kidney Diseases

Kidney Diseases

Another canine health condition that might cause wet dog patches is kidney disease. When your dog has kidney problems, they may have difficulty getting up after sitting or standing for lengthy periods, which may cause them to leave an odorless wet spot in the house.

There are many dog breeds that are more likely to leave wet spots, even if they do not have any other health concerns. For example, compared to long snouts, dogs with small noses, such as Boxers and Bulldogs, usually lie on their front paws, finding it difficult to get up and necessitating more frequent dog bathroom breaks.

9. Age

Urinary incontinence is more common in older dogs. The explanation for this is straightforward: as dog’s age, their muscles lose contractility and grow weaker.

All muscles, including those in the bladder and urethra, are affected. In other words, senior dogs have a harder time avoiding urine.

When age is a risk factor, dogs begin to leave wet spots as they reach middle age or later.

How to Treat Incontinence in Dogs?

How to Treat Incontinence in Dogs?

The therapy for urine incontinence varies depending on the reason. For urinary tract infections, hormonal decline, and other diseases, antibiotics or other medications are commonly used; surgery and dietary changes may be required for bladder stones. For the various causes of urinary leakage, alternative therapies, elimination of medications if they are causing adverse effects, or other forms of treatment for underlying diseases may be required.

1. Medications


Only when a vet recommends prescription medicine is it the best dog wet spot treatment. They can include pharmaceuticals that assist your dog’s bladder muscles in tightening up to keep in their urine until you take them outside and medications that minimize any worry, tension, or discomfort that may cause your dog to lose control.

2. Changes in Diet

Your dog’s nutrition may also play a big role in their wet patches, and it’s usually the simplest way to solve this canine health problem. Because they aren’t getting enough fluids, dogs that don’t drink enough water or consume food with low moisture content, such as dry dog chow, are more likely to have wet spots.

If your dog regularly drinks a lot of water, you might want to consider switching to canned dog food, which has a greater moisture content than kibble.

3. Surgery


Your dog may be able to avoid smelly, moist spots with surgery. However, there are certain things you could do at home to help them through the recovery process and avoid future damage and discomfort. If everything else fails and there are no inherent illnesses, such as heart disease, surgery may be possible.

This will entail eliminating any excess sphincter muscles your dog may have in order to prevent future dog wet spots.

Removing excess sphincter muscles will provide your dog with wider space in their pelvic area, allowing them to engage in regular activities without the leaking issues that these muscles cause.


If a potty-trained dog begins to leave wet marks, owners think that their canines are misbehaving. On the other hand, wet spots are more frequently than not caused by a medical problem rather than a behavioral one.

A dog that leaves odorless wet spots is most likely incontinent. As previously said, there are a variety of causes for urine incontinence, and therapy varies depending on the cause.

Some underlying causes are self-limiting and temporary, while others are more persistent and may need lifelong therapy. In all circumstances, you must work closely with your veterinarian to achieve the desired outcome for your dog.
