If your dog has started peeing in its sleep, you’ll need to find out the reason as soon as possible.

This doesn’t necessarily mean that your dog has a serious medical condition, but it can indicate one.

The more you learn about this behavior, the easier it will be to help your pup.

Reasons Your Dog is Peeing in its Sleep

There are a number of possible explanations for your dog peeing in its sleep. When you take the time to learn about these explanations, you can most likely find out why your dog is doing this.

1. Diabetes

If your dog has diabetes, they could have problems with peeing during sleep. Dogs with this condition tend to urinate a lot more than normal, which can lead to accidents. Diabetes is a very serious condition for both humans and dogs.

Some of the other symptoms of diabetes in dogs to look for include:

  • Lethargic behavior
  • Increased thirst
  • Weight loss
  • Increased appetite

There are effective treatments available for dogs with diabetes, but you’ll need to get yours diagnosed as soon as possible. This condition can usually be managed pretty well over the long term.

2. A Bad Dream

It is even possible that your dog peed in its sleep due to a particularly intense dream. Animal behaviorists have all but confirmed that dogs dream just like people. If your dog gets really worked up during a dream, it could end up wetting the wet.

3. Kidney Disease

Problems with your dog’s kidneys could also be responsible for this behavior. Dogs that have this condition tend to drink a lot of water, and sometimes they may urinate inside the house. If you have noticed your dog exhibiting any muscle weakness or disorientation in addition to peeing in its sleep, it might have kidney disease.

While there is no cure for kidney disease, it can be managed with medication. Your veterinarian will likely want to run some blood tests to diagnose this condition and find out how advanced it is.

4. Your Dog was Recently Spayed or Neutered

If you recently had your dog spayed or neutered, they might urinate inside the house for the first few days following the procedure. As annoying as this can be, it is perfectly normal under the circumstances. 

A dog that gets spayed or neutered can develop problems with their sphincter muscles, which can cause them to defecate in the house as well. While this issue is usually temporary, it can last for years if there are complications during the surgery.

5. Urinary Tract Infection

A urinary tract infection or UTI is often to blame when it comes to dogs peeing in their sleep. While this isn’t one of the more serious infections your dog can get, it still needs to be treated promptly.

It is normal for dogs with a UTI to drink a lot more water than usual, so pee accidents are not uncommon. If your dog wakes up with a full bladder, they might have an accident on their bed or the floor.

Some of the other symptoms of a UTI in dogs include:

  • Blood in urine
  • Cloudy urine
  • Licking near their urinary opening
  • Fever (if the infection progresses)
  • Frequent urination

You should take your dog to the vet right away if they are exhibiting these symptoms. It is crucial that you get this infection cleared up as soon as possible. If the infection is allowed to progress, it could do major lasting damage to your dog’s kidneys.

6. Neurological Issues

In some cases, a dog might urinate in its sleep due to neurological/brain issues. This could anything from dementia to spinal cord disease. These conditions are very serious and can be difficult to treat. If a certain part of your pet’s brain is affected, they may develop urinary incontinence.

Some of the other symptoms of neurological problems in dogs include:

  • Seizures
  • A change in your dog’s gait
  • Lack of coordination
  • Unresponsive demeanor
  • Excessive drooling

How to Keep Your Dog from Peeing in its Sleep

There are some helpful tips that you can follow to reduce the chances of your dog peeing in its sleep.

Take them out before you go to bed

Sometimes you can keep your dog from peeing in its sleep by just taking them out to go to the bathroom before you get into bed. The last thing you want is for your dog to go to sleep with a full or nearly full bladder.

Limit their water consumption

If your dog is drinking more water than usual due to a medical issue, you’ll want to limit their access. This can help with keeping their condition from getting worse while reducing the chances of accidents in the house.

  What to Do If Your Dog Bites Someone?

Take them to the vet

It might be necessary to take your dog to the vet, especially if their inappropriate urination is being caused by an underlying health problem. Whether it is a urinary tract infection or diabetes, you’ll need to get your dog the necessary treatment.


  • Diabetes is not an uncommon condition among dogs, and it can cause some of them to urinate in their sleep. This is due to the increased thirst that dogs with this condition often experience.
  • If your dog has an intense dream about something, they could end up urinating in their sleep.
  • Kidney disease is another common explanation for this behavior among dogs, as it too causes increased thirst.
  • If you recently had your dog spayed or neutered, they could have accidents in the house for the first few days.
  • In some rare cases, dogs that get spayed or neutered develop permanent conditions related to their sphincter or urinary tract.
  • A urinary tract infection could also explain why your dog is peeing in its sleep. This is not inherently a life threatening condition, but you’ll want to get it treated quickly.
  • Neurological problems like dementia or spinal cord disease can cause urinary incontinence in some dogs.
