Dogs are more afraid of irritating smells, such as lemon, grapefruit, essential oil, and perfume. You can also use pet-specific deodorants to prevent your dog from pooping in the same place again. But if you want to prevent your dog from pooping at home, it is best to train your dog to defecate at designated points and take your dog for a walk on time every day, otherwise your dog may poop in various places at home.
