Nepal has suffered its second major earthquake in two weeks and as emergency teams do their best to rescue people they will be relying on dogs for help.

Bryn the dog has just returned from the south Asian country where he helped search and rescue volunteers after the first quake.

The collie has been trained to help sniff out any people who might be stuck under rubble from collapsed buildings.

Leah went to meet Bryn and his rescue team to find out more.
