An anti-marking system includes an absorber and a connector that removably attaches the absorber to an article, e.g., a collar, worn by the pet. The pet may be inhibited from marking by absorbing into the absorber the fluid or scent that the pet produces when the pet marks a location and then after absorbing the scent into the absorber, attaching the absorber to the article worn by the pet. In one implementation, the system includes a dog collar and an absorbent pad that is removably attached to the dog collar.
