Delgado reappears in the second film, where he saves Papi Jr. from a deadly fall. Papi and Chloe, along with Sam, discover him and thank Delgado for saving their son, with Papi stating that he is forever in his debt. Sam calls Delgados owner who is wrapping up a big case and wont be able to pick him up for a few weeks, so Sam lets Delgado stay with Papi and Chloes family in the meantime.
Delgados main role is that he finds Alberto and Antonio (Degaldos sons) that he had regretfully abandoned as puppies at a police station, due to an incident in the past. Later, after helping capture the bank robbers, Chloe and her family eventually explain to Delgados sons why he did it, and they accept this from them and their father, thus earning him a place in Beverly Hills in the L.A. force for a while, and giving him and his sons more time to catch up a little.
Sometime later, the same rat and iguana from before help Delgado by presenting him with Chloes collar. Delgado sniffs it several times before he gets his sense of smell back as he goes to find Chloe. He eventually finds Diablo and defeats him by pinning him to the ground, although Diablo manages to slip away. Shortly after, Delgado becomes a member of the police force again and bids Chloe farewell before he leaves with his new partner.
Later, Chloe and Delgado become stranded in a desert after jumping off a train they stowed away on earlier. They eventually encounter a large group of stray Chihuahuas led by Monte, who save them from three vicious mountain lions. Chloe and Delgado then stay for a short time at the Chihuahua packs birthplace.
Along the way, Chloe constantly pesters Delgado by asking him agitating questions. Later, while Delgado was asking for help from one of his German Shepherd friends, Chloe gets tricked by a rat named Manuel and an iguana named Chico, who talk her into giving them her diamond collar. When Delgado finds out, he quickly becomes furious with her because that collar was evidence to where she lived.
