SAN ANTONIO (AP) — Federal authorities have raided a San Antonio school that trains veterans on dog-handling.

Councilman Manny Pelaez tells the San Antonio Express-News that the Wednesday raid of Universal K9 was part of “an ongoing FBI investigation into fraud allegations of a business operator.”

The raid comes less than a month after Universal K9 filed defamation and breach of contract lawsuits against two former students. The lawsuit says Universal K Nine Inc., which does business as Universal K9, began as a for-profit business in 2010. Veterans may use the GI bill to cover the dog-handling course costs, which amount to $12,500 for a 10-month course.
