Author: Amanda Shotsky (Reporter) Updated: 10:34 PM PST January 7, 2021 SAN DIEGO — The San Diego Humane Society is investigating fliers posted on Fiesta Island claiming that multiple dogs have gone missing. The fliers which started popping up this week say that "a dog a week has gone missing since November." They also claim that one dog was poisoned and another left with glue on it's body. While groups like Fiesta Island Dog Owners (FIDO) say that they've been notified that the whole thing is a hoax, others sharply disagree.
