If some moron has let their dog loose at 1am in 35º weather again, here's what you can do:

If it's vicious, call 911.

The Humane Society of Huron Valley handles all cases. Call them at 734 662 5585. They are staffed from 8am - 10pm and have answering machines for off-hours. Leave a message with your name, phone number, the address the dog belongs to / was last seen, the time, and a description of the situation.

If you lost a dog, the lost and found on Craigslist is a possibility.
