Old Black & White Mexican Film With A Funny Talking Horse?

[EVILONE]

There's an old black and white Mexican movie about a guy (cowboy style) and his talking horse. It's from maybe the 40's or 50's and is in Spanish. It's really funny. I used to have it recorded on a VHS tape but it got misplaced or recorded over and is gone for good. Anyone know what this movie is called? I've searched everywhere for years and can't find it. I would love to see it again for the laughs. Any help would be greatly appreciated. Again this is an old Mexican film, not Mr. Ed or any American stuff. Thanks!

Any links for that movie?
