<P> The show features an eight - year - old Latino boy named Diego ( voiced by Jake T. Austin , seasons 1 -- 3 ; Matt Hunter , season 4 ; Brandon Zambrano , season 5 ) who rescues animals around the world . His cousin is Dora ( Kathleen Herles ) from Dora the Explorer , as revealed in multiple shows , usually without Boots by her side . Diego was first introduced in an episode of Dora the Explorer entitled `` Meet Diego ! '' ( originally voiced by brothers Andres and Felipe Dieppa ) . Diego has a jaguar companion named Baby Jaguar ( voiced by Thomas Sharkey ) who assists him in rescuing the animals . Baby Jaguar also appears in Dora the Explorer but inconsistently ; on Go , Diego , Go ! he takes a more active role , which includes being able to speak . </P>
