Mario G. Obledo, a civil rights leader, called for a boycott of Taco Bell if the company did not end the ad campaign.

[10] In July 2000, Taco Bell ended the chihuahua advertisements,[6][12] ended its relationship with their creator TBWA, and replaced the company's president, after same-store sales fell by 6% in the second quarter of 2000, the largest such decline in Taco Bell history.

[14] Voice actor Tom Kenny, who is a friend of Alazraqui, said that Hispanic advocacy groups lobbying for the end of the campaign led to the cancelation of the Taco Bell dog.
