What to Spray on Carpet to Keep Dogs From Peeing

Dealing with a dog who pees in the house is a pain, but there are steps you can take, especially if your otherwise perfect pooch likes to piddle on the carpet. Dog urine has an unpleasant smell and over time the odor becomes more difficult to remove. To prevent your dog from urinating on carpets while you train it to urinate outdoors, you may use certain commercial repellents or home remedies. Dogs have very sensitive noses, so often a strong smelling repellent sprayed on their usual pee spot will be enough to dissuade your dog from peeing. It's important to clean the areas well before you apply any solutions, especially if the dog has urinated on the carpets as dogs tend to return to places that have a urine odor. Also, be sure to spot test any of these repellents before spraying large areas to be sure no discoloration of your carpet occurs.

Commercial Repellents


Commercial repellents are available in the form of sprays and contain different chemicals or natural compounds such as cayenne pepper that dogs don't like and will avoid. If the dog has already soiled the carpet, clean it using an enzymatic cleaner or vinegar, and allow the carpets to dry completely. Spray the repellents generously and reapply as indicated on the label of the product you use.

White Vinegar


White vinegar is not only an effective carpet cleaner and urine odor remover, but it also acts as a repellant. Prepare a solution of white vinegar and water in a 1-to-1 concentration and spray it over your carpets and the areas where your dog likes to urinate. Dogs don't like the smell of acetic acid and are likely to avoid the areas that are sprayed with this solution.

Lemon Juice


Mix lemon juice (commercial or freshly squeezed) with water and sprinkle it on your carpets. This smell is pleasant for people, but will keep your dog at bay. The citric acid is also effective if you want to clean and remove urine odor from carpets.

Rubbing Alcohol


Isopropyl alcohol, better known as rubbing alcohol, is an effective disinfectant and has antibacterial properties. Its powerful scent is not agreeable for canines. Dilute rubbing alcohol using one part alcohol and one part water and spray it on your carpets. Reapply the mixture weekly or after each cleaning of the carpets.



Ammonia has a powerful smell dogs dislike. However, the smell of ammonia is similar to the dog urine smell you want to cover, so you might want to save this solution if all others fail. Dilute the ammonia with water and spray it over the carpets.
