“Lab Rescue will find a new home for this dog if its owners do not come forward,” Push said in an e-mail early Wednesday morning.

Roberts’s rescue dog, Katie, disappeared in Bethesda on Saturday, shortly after the Emmy Award-winning journalist adopted her.

The search for the 5-year-old black Labrador retriever generated a local media frenzy when it was announced Tuesday and has led to reports of numerous supposed sightings.

“We are using tracking dogs to try to find her,” Push said. The most recent reported Katie-sighting was Tuesday night in Chevy Chase.

According to Push. the tracking dogs caught her scent about five miles from Roberts’s Bethesda home, along Western Avenue NW between the traffic circles at Connecticut and Utah avenues.

Anyone with information about Katie’s whereabouts can call Lab Rescue at 703-589-5034 or Montgomery County Animal Emergency Line at 240-773-5900.
