Join Archway Pet for our annual Howl-o-ween pup party at Leavitt Street Inn on Sunday, October 18, from 11am to 2pm. Bring your best-dressed dog for a costume contest, drinks, and an afternoon with Chicago's indie pet community. This year the party doubles as a fundraiser for Mercer Animal Rescue, helping Bev Mercer raise the last $891 to repair her transport van so it can get back to rescuing puppies from Mississippi. Come hang out, meet local vendors and rescues, and help get Bev's van back on the road.
