Chicago-Specific Tips

• CACC's online database is searchable at chicagoanimalcare.com — check it daily and visit in person every 2–3 days.
• Chicago's lakefront trail is a major corridor for lost dogs. A dog that goes missing near the lakefront may travel north or south along the trail for many miles.
• The Chicago River and its branches serve as corridors in the city — dogs follow waterways. Check areas near the river if your dog went missing near a riverside neighborhood.
• During winter months, lost dogs in Chicago face hypothermia risk rapidly. A dog lost overnight in January is a medical emergency — frame your alerts with appropriate urgency.
• Chicago neighborhoods have very active neighborhood Facebook groups (Logan Square, Wicker Park, Lincoln Park, etc.) — post in your specific neighborhood group in addition to the general lost pet groups.
• PAWS Chicago has a lost and found database at pawschicago.org — submit a report there as well.
