Why Is My Dog Suddenly Having Accidents

Why Is My Dog Suddenly Having Accidents?

Having a well-trained and housebroken dog is something that every pet owner strives for. So, when your dog suddenly starts having accidents inside the house, it can be both frustrating and confusing. There are several possible reasons why a previously housebroken dog may start having accidents, and it’s important to identify the cause in order to address the issue effectively.

1. Health Issues: One of the most common reasons for sudden accidents in dogs is an underlying health problem. Urinary tract infections, bladder stones, diabetes, and kidney disease can all cause increased urinary frequency and accidents. If your dog is having accidents along with other symptoms like increased thirst, frequent urination, or changes in appetite, it’s important to consult a veterinarian.

2. Stress or Anxiety: Dogs can sometimes develop house soiling behaviors as a response to stress or anxiety. Major changes in the household, such as a new baby, a move, or the addition of another pet, can trigger these behaviors. Providing your dog with a safe and comfortable space, along with positive reinforcement training, can help alleviate their anxiety and reduce accidents.

3. Aging or Cognitive Decline: As dogs age, they may experience cognitive decline, which can affect their ability to hold their bladder. This condition, known as canine cognitive dysfunction, can also lead to confusion, disorientation, and changes in behavior. If you suspect your dog’s accidents are due to cognitive decline, consult your vet for possible treatments and management strategies.

4. Lack of Routine: Dogs thrive on routine, so any disruption in their daily schedule can lead to accidents. Changes in feeding times, walking schedules, or even the location of their potty area can confuse them and cause them to have accidents. Reinstate a consistent routine and make sure your dog has access to their designated potty area at all times.

5. Marking Behavior: Dogs may start marking their territory inside the house as a way to establish their presence or respond to a perceived threat. This behavior is more common in unneutered males, but can also occur in females. Neutering or spaying your dog can help reduce marking behaviors, but it’s important to consult a professional dog trainer to address the issue effectively.

6. Inadequate House Training: Sometimes, accidents can occur simply because the dog was not properly house trained to begin with. If your dog was not given consistent and positive reinforcement training as a puppy, they may never have fully learned where it is appropriate to eliminate. In this case, it’s essential to go back to basics and retrain your dog using positive reinforcement techniques.

7. Urinary Incontinence: Some dogs may experience urinary incontinence, which is the inability to control their bladder. This condition can be caused by hormonal imbalances, weak bladder muscles, or certain medications. If you suspect your dog has urinary incontinence, it’s important to consult your vet for a proper diagnosis and treatment options.

8. Submissive or Excitement Urination: Submissive urination is a common issue in young or anxious dogs. They may urinate when they feel intimidated or when greeting people or other animals. Excitement urination, on the other hand, occurs in dogs that become overly excited or stimulated. Both issues can usually be resolved through training and building confidence in your dog.

9. Lack of Access to the Outdoors: Dogs need regular access to the outdoors to eliminate properly. If your dog is not able to go outside frequently enough or is confined to a small space for long periods, they may be forced to have accidents inside. Ensure that your dog has sufficient opportunities to go outside and provide them with a comfortable and accessible potty area.

10. Changes in Diet or Feeding Schedule: Sudden changes in a dog’s diet or feeding schedule can disrupt their digestive system and lead to accidents. It’s important to introduce any dietary changes gradually and maintain a consistent feeding schedule to avoid gastrointestinal upset.

11. Marked Territory by Other Animals: If you have multiple pets, accidents can occur when one animal marks their territory, causing other animals to respond in kind. This can create a cycle of marking behaviors and accidents. Properly address marking behaviors and ensure all animals have separate spaces and resources to prevent territorial disputes.

12. Lack of Supervision: Dogs that are not properly supervised may have accidents simply because they were not taken outside in time. It’s important to closely monitor your dog’s behavior and provide them with frequent opportunities to eliminate outside, especially after meals or naps.


1. How can I determine if my dog’s accidents are due to a health issue?
Consult with your veterinarian to rule out any underlying health problems that may be causing the accidents. They may recommend a physical examination, urine tests, or other diagnostic procedures.

3. My dog has been house trained for years, why is this suddenly happening?
There could be several reasons for this sudden change, such as a health issue, aging, or a disruption in routine. Evaluate any recent changes in your dog’s environment and consult with a veterinarian if the accidents persist.

4. How can I prevent my dog from marking inside the house?
Neutering or spaying your dog can help reduce marking behaviors. Additionally, providing consistent and positive reinforcement training, along with managing their environment, can discourage marking.
