A puppy called Penny could soon be reunited with her worry-stricken U.S. owners after she went on a nearly 2,400-mile (3,860-km) road trip that took her to an Iowa truck stop and a Pennsylvania pet hospital, her family says.

The floppy-eared Vizsla has one more stop before returning home to Washington state. She has to travel from Pennsylvania, where she has been in foster care, to the District of Columbia for a free ride home from U.S. carrier Alaska Airlines, her owners said in a message on a Facebook page devoted to finding her.

"When she went missing, we thought she ran off and we were never going to see her again. We're just happy knowing she's alive," Kendra Brown, Penny's owner, told Pittsburgh broadcaster WPXI. "I'm sure if she could talk, she'd have quite a few adventures to talk about."
