Understanding Dog Marking in House and How to Stop It

Marking is a natural behaviour for dogs, but it can become a nuisance when it is done inside the house. This article will discuss why dogs mark their territory, why it happens inside the house, and what you can do to stop it. With the correct understanding and action, you can keep your home free from dog marking.

What is Dog Marking?

Dog marking is a behaviour that dogs use to communicate with other dogs and mark their territory. It is a scent-based marking behaviour that involves urinating, defecating, and rubbing their bodies on objects to leave a scent. Dogs will often mark areas that they consider to be theirs, such as their bed or food bowl.

Marking is a natural behaviour for dogs and they will often do it outside the house, too. However, it can become a problem when they start marking inside the house, as it can be difficult to clean up and it can cause a bad smell.

Why Do Dogs Mark Inside the House?

There are several reasons why dogs may start marking inside the house. One of the most common reasons is due to stress or anxiety. When a dog is feeling anxious or stressed, they may start to mark inside the house as a way to make them feel more secure in their environment.

Other reasons why a dog may start marking inside the house include:

  • The presence of a new pet or person in the house
  • A change in the home environment
  • A lack of stimulation or exercise
  • A lack of attention from their owners
  • A medical condition such as a urinary tract infection

It is important to understand why your dog is marking inside the house so that you can take the necessary steps to stop it.

How to Stop Dog Marking in House

If your dog is marking inside the house, it is important to take steps to stop the behaviour. The first step is to identify and address the underlying cause of the behaviour. For example, if the behaviour is due to stress or anxiety, you may need to provide more attention, exercise, and mental stimulation for your dog.

You can also take steps to discourage the behaviour, such as:

  • Cleaning up any urine or faeces as soon as possible to remove the scent.
  • Making sure to keep the house clean and clutter-free.
  • Providing plenty of toys and activities to keep your dog mentally stimulated.
  • Giving your dog plenty of attention and exercise.
  • Using positive reinforcement techniques to reward your dog when they don't mark.
  • Using products such as pheromone sprays or diffusers to help reduce your dog's stress levels.

It is also important to take your dog to the vet to rule out any medical conditions that may be causing the behaviour.


Dog marking in house can be a nuisance, but it can be prevented with the correct understanding and action. By identifying and addressing the underlying cause of the behaviour, providing plenty of attention and exercise, and using positive reinforcement techniques, you can help stop your dog from marking indoors. With the right approach, you can keep your home free from dog marking.
