Nubs may be getting most of the publicity, but he wasn't the only Iraqi dog who was rescued by American troops in Iraq and sent to a new home in the U.S. this past weekend.

On Saturday, Liberty and K-Pot, two puppies rescued off Iraqi streets by U.S. troops who went on to serve as sanctioned security dogs for the unit who adopted them, took their first steps on American soil.

Liberty and K-Pot are SPCA International’s first emergency rescues from the war zone through the Operation Baghdad Pups program.

The program was started after an earlier rescue, which culminated with the Valentine's Day arrival of Charlie, a black-and-white puppy and unit-mascot for Charlie Company serving in Iraq.

Rescued from the streets of Baghdad as a puppy and nursed back to health, Charlie had his trip home sponsored by SPCA International and I Love Dogs, Inc.

"Working together, we can help rescue these animals who have meant so much to these American heroes who put their lives on the line everyday," SPCA International says on the special web site it has created for Operation Baghdad Pups.

Saturday's arrivals, Liberty and K-Pot, were both working with the Army unit, but were not approved to go with the unit when it relocated.

"If SPCA International had not come to the rescue in time, K-Pot and Liberty would have been left to the harsh war-torn streets and Iraqi civilians who are sometimes hostile to dogs who have befriended our U.S. troops," the SPCA said in a press release.
