abused dog?

sgbk

I saw a dog chained up outside of the Associated Grocery Store on 5th ave between President and Union at around 9:30. The dog was some sort of short hair mixed breed and is all brown. The dog was clearly malnourished as you could see its spine and was shaking in the cold. The dog also appeared to have either a sore or missing fur from some sort of injury on it's right leg. I attempted to call the ASPCA and they are closed for the evening. I also tried to report to 311 and their animal rescue is closed as well. I am just hoping someone will see this dog (during business hours) or can locate its home and report the person responsible for this to the ASPCA. This animal is clearly suffering. If anyone can help, please do.
