Finding urine spots around the house can be frustrating, but it’s important to understand that dogs mark with urine as a form of communication.
Marking isn’t always the same as a house-training issue—it can stem from stress, territorial instincts, or even medical concerns. Here’s a closer look at why dogs mark indoors and how you can prevent it.
Why Is My Dog Peeing in the House?
Medical Concerns
Even well-trained dogs may have accidents if there’s an underlying health issue. Urinary tract infections, bladder stones, incontinence, or other medical problems can cause changes in elimination habits. Always consult your veterinarian first if your dog suddenly starts peeing in the house.
Marking vs. House-Training Accidents
There’s a difference between incomplete house-training and urine marking. Dogs typically mark by leaving small amounts of urine on vertical surfaces, while accidents often involve larger puddles.
Dogs may feel the need to mark when:
- A new pet enters the home
- A new baby arrives
- A new adult begins spending time in the house
- You move homes, especially if the new place smells like other animals
How To Stop Dog Urine Marking
Spay or Neuter
The most effective way to prevent marking in unaltered dogs is to spay or neuter before maturity. While this can reduce marking in older dogs, it may not eliminate an already established behavior.
Use Enzymatic Cleaners
If your dog marks indoors, thoroughly clean the area with an enzymatic cleaner (such as Nature’s Miracle or Simple Solution). These products break down the proteins in urine that trigger repeat marking. Standard cleaners won’t fully remove the scent.
Supervise and Redirect
When bringing a new dog into your home:
- Keep them on leash and supervised initially.
- If you see signs of marking, quickly redirect them outside.
- When left unsupervised, crate or confine them in a safe space where marking isn’t possible.
Prevent Marking on New Items
If your dog has a history of marking, continue supervision around new furniture or upright objects, as these are common marking targets.
Address Anxiety
If a neutered dog continues marking despite your efforts, the cause may be anxiety or stress. In these cases, working with a veterinarian, trainer, or veterinary behaviorist is the best approach.
Dog urine marking can be a challenging behavior, but with patience, proper cleaning, and proactive management, it can be greatly reduced or prevented.
Start with a vet check to rule out medical issues, and then focus on training, environment management, and stress reduction to help your dog succeed.
