Control Dog Marking in Your Home

Dogs and cats are hypersensitive to smells and live in a scent-centered world. They instinctively spray urine to mark their territory. The SprayAlert® Alarm (US Patent 6,860,239) instantly emits a startling sound when sprayed by urine (or any other moisture).


Place the urine sensor in the spots where the pet typically marks. When sprayed, the alarm sound typically stops the marking, limits damage, and can act as a future deterrent. Redirect the dog to the correct area and reward for good behavior. Avoid punishment.


Immediate feedback for the dog is essential to modify behavior. Use this as a training aid for dog marking on furniture  and elsewhere in homes. Effective as a dog or cat urine/pee alarm to notify you immediately for quick cleanup.

The SprayAlert is an electronic alarm for detecting cat and dog urine/pee spraying and marking as it happens. 

  • Detect immediate pet urine spraying and marking to minimize damage to home, furniture.

  • Dog training to stop or reduce spraying behavior in some cases. A good training candidate is a dog that is marking habitually in the same place, in a few spots or less. Cats typically do not respond well to training. For them, addressing behavioral issues is usually the best solution.

  • Monitor areas previously sprayed. Follow progress of preventative measures.

  • Identify sprayer for medical assessment in multipet households.

  • Manage cleanup of habitual sprayer, dogs or cats


Before using this product, understand the cause of your pet's marking. Always first address medical and stress issues. It's primary use is for territorial marking cases; not for puppy training.
