I haven't seen it (well, maybe on TV when I was 6, but I don't remember it). Here's what Bill Cotter has to say about it in his Disney Television book:

Pablo and the Dancing Chihuahua
Airdates - Part 1: 1/28/68, 6/23/68, 8/20/72.
Part 2: 2/04/68, 6/30/68, 8/27/72.
Cast: Armando Islas (Pablo), Francesca Jarvis (Helen Gordon), Walker Tilley (Caretaker), Manuel Rivera (Manuel).
A young boy finds adventure in the desert as he searches for his missing uncle. Pablo's quest gets off to a bad start when he's caught trying to cross the border between Mexico and the United States, but he sneaks away while the border officials are examining the papers of Helen Gordon, an American tourist. Her pet chihuahua follows him as he runs into the desert.

Production Notes:
- This episode, shot on location in Arizona, took two years to film. The production company had to plan for the normal growth of the young star so scenes shot over the 2-year span matched and didn't make his 6-inch change in height noticeable.
- This show was released theatrically overseas in 1969.
