Narcoleptic Dog Passes Out at Sight of Postman

Five year old Bearded Collie cross Mable suffers from canine narcolepsy, a rare sleep disorder with limited treatment options. Triggered by excitement, her condition renders her unconscious for up to twenty seconds at a time.

Her owner, Trevor Gliddon, does his best to protect Mable by avoiding public situations that could trigger an episode, but some forms of excitement are unavoidable. “Mable does get excited when she meets other dogs because she’s so friendly. Then all of a sudden she’ll be out like a light. She’s only gone for a couple of seconds.”

While painless, Mabel’s narcolepsy is sometimes a source of confusion, leaving her disoriented. “From her point of view one moment they’re all on top of each other and the next the other dogs will be 20 meters away. This does tend to puzzle her as suddenly every one else has moved on. It’s like time travel to her.”

  1. That is so bizarre. If there are no problems for her beyond the sudden drop, then we guess she’ll be OK. Too bad there isn’t a way to fix it.

  2. I can only imagine how scary this was for dad the first few times this happened. Too bad there isn’t a way to know what she’s thinking/seeing while she’s out, as it seems she’s still barking at the excitement.

    Happy she found an understanding and accepting family.

  3. Poor Mable At least she has a very understanding owner. I wish she could find a canine buddy that will keep her company and help her when she has a episode.
