Lost Mini Aussie: Red/Brown, Last Seen 1/20

Mini Australian Shepherd, red/brown hair with tan spots and white undercoat. Small underbite. Barks at strangers. Familiar with and loves kids. She went wandering with our other dog and he came back without her, which is very unusual. He seemed worried and has looked for her since. She had a collar with AirTag on that last dinged at 1:30pm on 1/19 at the location of Halstead and Coral Sea Road. Then the next morning (1/20/25) it updated location to a ditch where we found the latched collar and no dog. Her approximate size is about a foot tall, she is a little chunky for her breed.
