Cleaning up messes is an unavoidable part of pup parenting, but peeing the bed is something more often related to human children than fur babies. You can’t send your chihuahua to bed with a pair of pull-ups, and waiting for them to grow out of it won’t work either.

Whether your chihuahua is still a puppy or fully mature, you can’t compare a urine-soaked chihuahua bed to a toddler’s wet sheets. When a chihuahua pees the bed, potty training is rarely the issue. Here are the more likely reasons why your chihuahua pees the bed.

When They’re Asleep

For kids, wetting the bed at night is a normal part of growing up. Most kids grow out of it before their age hits the double digits, but that’s not the case for your chihuahua. If you find your chihuahua’s bed wet with urine after he wakes up, his young age likely has nothing do with it. Your first thought shouldn’t be about better potty training, it should be concern for his health.

Hormone Responsive Urinary Incontinence

Hormone responsive urinary incontinence is a condition most often affecting middle-aged, spayed female chihuahuas and occasionally seen in younger females and males. According to dogster, the issue has to do with a chihuahua’s estrogen levels. When a female chihuahua is spayed, her ovaries are removed. This leads to an automatic decrease in estrogen production. Reports indicate estrogen contributes to the control of a chihuahua’s urethral sphincter (the muscle that allows a chihuahua to “hold it”).

With less estrogen, the sphincter becomes more relaxed. chihuahuas experiencing hormone responsive urinary incontinence leak urine when they’re not consciously thinking about holding their bladder. As the chihuahua ages and her sphincter naturally becomes weaker, the problem becomes more prominent. The condition is treatable, but it’ll require a visit to your vet.

Urinary Tract Infection

As with humans, urinary tract infections are common in chihuahuas. It happens when bacteria invades the urinary tract and causes symptoms like painful urination, blood in the urine, and decreased bladder control. A UTI is often the reason a chihuahua pees the bed.

A chihuahua suffering with a UTI doesn’t “forget” their house training like their owner thinks. The infection in their urinary tract makes it difficult to stop the flow of urine when they really need to go. It can also make them feel like their bladder is full to bursting when it actually isn’t. This means they’ll need more frequent bathroom breaks, and they might not get out of bed fast enough. A round of antibiotics should clear up the infection and fix the problem.

Other Medical Issues

There are several medical conditions that can affect a chihuahua’s bladder control while they’re asleep. Possibilities include bladder stones, spinal cord injury, diabetes, and cognitive disorders. General incontinence, or the natural weakening of the urethral sphinchter, also becomes more common as chihuahuas age.

For many urinary-related medical issues, the problems are progressive. A chihuahua might slowly leak small amounts of urine for several nights before you realize what’s happening. After a few weeks, there’s potential for that small leak to get worse. Eventually, the chihuahua might empty his entire bladder without waking up. Finding your chihuahua’s bed wet with urine after they wake up is always a reason to visit a vet.

When They’re Awake

Peeing on the bed when they’re awake poses different problems than when a chihuahua pees the bed when they’re sound asleep. The medical issues listed above could still be to blame, but chihuahuas generally do everything they can to avoid soiling their sleeping areas. It stems from a wild chihuahua’s instinct to keep their den clean and sanitary. If something is overriding that instinct, it could be either medical, emotional, or behavioral.

Stress, Fear, and Anxiety

When your chihuahua is frightened by thunder, worried about an unknown house guest, or feeling anxious for any reason at all, their bed is a place of comfort and safety. That type of emotional distress can cause a chihuahua to temporarily lose control of their bladder or behave in ways they normally wouldn’t. If they’re afraid of a person or another animal in the house, there’s also the chance they’ll pee on their bed because they’re too scared to leave and go to their normal potty spot.

Indoor accidents are also associated with separation anxiety. Pet Carrier says,

“Chihuahuas that have this issue tend to grow extremely distressed when left alone in the house, and one of the symptoms is urinating and defecating indoors. If your chihuahua pees on your bed every time you leave them home alone, speak to a vet about separation anxiety. The chances are, your chihuahua is leaving you a message in a place that they know without a doubt that you’ll find it.”

The only way to stop the bed wetting is to address the underlying emotional issue. Observe what happens before your chihuahua pees on their bed, and consider that context to determine if its affecting your chihuahua’s urination.

Marking

Urine marking is something both male and female chihuahuas do out of instinct. They mark trees and fire hydrants along their daily walks to tell other chihuahuas they’re claiming that territory. Some chihuahuas also mark around the house to warn off potential intruders.

If your chihuahua’s confidence recently took a hit or he’s feeling threatened, he might start marking inside. You’ll know he’s marking and not breaking his housebreaking rules when he only lets out small amounts of urine in strategic places. Most chihuahuas prefer to keep their beds clean, but an insecure pet trying to protect their belongings might go to extreme measures to keep others away from what’s theirs.

This is most common when a new family member (human, canine, or feline) is introduced to the house. Helping your chihuahua feel more confident and using positive reinforcement to show them where it’s appropriate to pee and where it isn’t will help.

Figuring out why your chihuahua pees the bed is the first step in preventing it from happening. It’s important to remember that no matter how frustrating it is to wash your chihuahua’s bed on a regular basis, punishment isn’t the answer.

Whether their bedtime troubles are caused by a medical issue, stress, or the natural instinct to mark their territory, being angry will only add to their confusion. It’s always a good idea to talk to your vet for insight into your pet’s urinary health and tips for relieving stress and anxiety.

I recently adopted a male chihuahua. he has been neutered. he will be playing and just hike where ever he is…. he is housebroken, we have a dog door so he can go out as he needs to. he also has a toy that he acts like a little puppy. he will act like he is nursing and even do his paws like Ive seen kittens do.
