U.S. Immigration and Customs Enforcement is in the process of adding 10,000 more deportation officers to its workforce and now plans to supplement those men and women with robot dogs during interior immigration enforcement operations.

A federal procurement notice published by ICE late last week revealed the agency will drop up to $2 million to purchase the four-legged K-9 units, known as “Spot,” from Boston Dynamics. The contract was first reported by ABC News.
