The purpose of the present invention is to provide a cheap defecation pad to a person who raises a dog but feels a financial burden due to the price of a defecation pad, by printing a sponsored advertisement on the defecation pad. When an advertisement using red and green colors is printed on the defecation pad, an advertiser can advertise to a target person who raises a dog, and a consumer can purchase the defecation pad with the printed advertisement at a low price. The dog has red-green color blindness, and thus cannot differentiate the advertisement from the defecation pad even though the advertisement is printed on the defecation pad.;COPYRIGHT KIPO 2014
