The 4- to 5-year-old male, brown Chihuahua was paralyzed from the waist down as a result of the injury, said Scott Delucchi, spokesman for the humane society. The dog had been shot "with some kind of projectile," according to the society's medical team.
The dog was "humanely euthanized" on Aug. 1 "after tests confirmed his dire condition," Mr. Delucchi said.
Residents of 1300 block of Henderson Avenue in Menlo Park found the dog in front of their home unable to walk and in pain.
X-rays confirmed the dog had a severed spine, Mr. Delucchi said.
The human society is looking for leads in what "would most certainly be a felony animal cruelty case," he said. Anyone with information is asked to call the society's lead investigator, Chrstina Hanley at (650) 340-7022, ext. 384.
