Dog who spent 419 days in Texas animal shelter returned after one day with new owners Humane Society of Central Texa By: KXXV Staff and last updated 2021-03-31 22:14:14-04 WACO, TX â Rusty thought he was the luckiest dog in Waco. At just 2-years-old, Rusty spent half his life at the shelter. His owners surrendered him as a puppy in February 2020 because he was hyper. Rusty was placed in a foster home for two months and then was sent to a rescue in Idaho. Two months later, the rescue sent him back to Waco because he was not dog-friendly and they weren't able to place him in a home.
