Pongo, a 6-month-old Rottweiler mix, was found four days ago by a Riverside Animal Control officer. The officer answered an anonymous call and found Pongo wrapped in a trash bag in a dumpster at a Riverside apartment complex.
The puppy was rushed to Western Riverside County/City Animal Shelter in Jurupa Valley in an emaciated and lethargic state.
Vets weren't sure he'd make it, but they went to work with fluids and medication. Pongo, named by staffers, has gained weight and improved dramatically.
The dog will remain under observation until a new owner shows up. Anyone interested in adopting Pongo should first contact John Welsh with Riverside County Animal Services at jcwelshrivcocha.org.
