A Glendora family’s quiet backyard turned into a late-night wildlife drama Wednesday when a mountain lion attacked their dog, which survived the encounter, according to local television footage. Neighbors in the foothill area said the sighting left people rattled as big-cat encounters creep closer to homes this spring. Officials had not released a fuller statement when the short report went up, leaving key details about the lion and the pet’s condition unclear.
The brief item was posted Wednesday by FOX 11 Los Angeles, which ran a short video and noted the dog survived. The station’s post, published May 20 at 10:13 p.m., offered few specifics about where in Glendora the attack occurred and did not include an on-camera statement from wildlife or police officials.
Foothill sightings and recent attacks
Mountain lion encounters have been popping up across nearby foothill communities this season, with a late-night attack in Glendale and an April backyard killing in Yucaipa putting residents on edge. CBS Los Angeles reported on the February Glendale incident, and a video-captured backyard attack in Yucaipa was detailed by backyard horror in Yucaipa. State wildlife officials told reporters that elevated mountain lion activity in spring is not unusual as cats move and young animals disperse.
How residents can protect pets and report sightings
Residents living near the foothills are urged to bring pets indoors at night, keep small dogs close and on a short leash during walks, and minimize landscaping that attracts deer or other prey animals. California State Parks recommends avoiding solitary hikes at dawn or dusk and keeping children and pets within arm’s reach when near trails. If you spot a mountain lion or your pet is attacked, wildlife groups urge saving any photos or video and reporting the sighting so biologists can investigate and track the animal. If you encounter a lion, do not run; instead make yourself appear large, shout and throw objects if necessary to haze the cat, per National Park Service guidance.
If you witnessed the Glendora incident or have video from the area, contact local police and report the sighting to the California Department of Fish and Wildlife so biologists can follow up. We will update this story when officials provide more information.
