Wiener Dog On The Loose -- At The Ballpark ... Players Can't Catch Him

The El Paso Chihuahuas -- a Triple-A baseball team -- had a great idea to get fans amped up for the start of their game ... have a race with a bunch of Dachshunds (wiener dogs).

The Wienerschnitzel weenie dog race went smoothly in the beginning ... then all hell broke loose when one pup broke free from the pack and turned the field into his own personal playground.
