(NEWSER) – Walking your dog in San Francisco? Don't let it eat any meatballs you may find on the street. Police in the city say they have found dozens of meatballs suspected to be poisonous in a Twin Peaks neighborhood where a similar incident happened last year. An officer says she found 34 meatballs hidden in carports, behind stairwells, along curbs, and in bushes on Saturday. She says a resident handed her another ball of raw meat she took from her dog.
