Narcoleptic dog falls asleep when excited by the postman

Excitable dog Mabel paws the door in a frenzy as mail is delivered - then instantly falls asleep due to narcolepsy.

The bearded collie's rare canine version of the disorder kicks in when she is over-wrought by thrills like the postman's arrival or meeting other dogs.



Owner Trevor Gliddon, 46, said: "She goes down like she's been shot, but she's only gone for a couple of seconds. Then she wakes up as right as rain."

But the photographer, of Tavistock, Devon, says Mabel, five, is confused if she crashes out while playing with pals - then wakes to find them gone. He said: "This tends to puzzle her as suddenly every one else has moved on. It's like time travel to her."
