A man was able to find his dog in the mountains by using a PA system.
A dog
Robert Bluntsworth feared the worst when his pooch Matrix disappeared deep in the forests of Northern California, but was able to use the address system to trace him thanks to a friend.
He told LADBible: I was driving around the mountain roads calling his name for about two hours and posted him up on all the local groups on Facebook.
''My buddy in Texas called me freaking out and told me to set up the PA system and send his name through the mountains.''
Bluntsworth turned up the volume on the system which allowed him to track down Matrix within minutes.
Robert explained: ''He was gone for four hours but with five minutes of sending his name through the mountains I saw him darting through the wood finding his way back home.
''He was all muddy and did look a little embarrassed. I was so happy, and he looked happy because I was happy.''
