The principle of dog toilet inducer is to attract dogs to the designated place to excrete by simulating the smell and taste of dog urine.

The main ingredients of dog urine inducers are usually a series of synthetic compounds, such as urea, uric acid and urea. Dogs in the wild will often choose to urinate where other dogs have left their urine, as a way of socializing and establishing territory. Therefore, when training a dog to excrete in a designated place, the dog urine inducer can simulate the smell of other dogs' urine and trigger the dog's instinctive behavior so that it chooses to excrete in the designated place. In addition, dog urine inducers also play a role in masking other odors.
