I've been following reports of dogs being used to detect epilepsy seizures before they begin for quite sometime. It does tend to be rare and not necessarily breed specific. If Elkies have a trait for it, that's great!!! :d :D The dog has to be more sensitive than others, apparently. I've read where mutts and purebreds both were found to have the 'gift'.
There is one young boy at the school where I work who has a small Rough Collie as his service dog. (Yes, she wears the official vest) He suffers from severe grand mal seizures, but they can be sometimes controlled by meds worn on his arm. If she nudges him, he "injects" the medicine. Sometimes when the meds aren't working, she will put her nose on his waist. That's his signal to sit down. She will lay quietly next to him until it's over. She will alert nearby adults also. (barking)
She's a sweet little thing. It's very difficult to ignore her when she puts her nose in my hand :rolleyes: But I manage to :) She did it again on Monday when I said hi to him.
His parents adore her because she gives their son the best chance to have a fairly normal life. He was in a gym class that I subbed in last year. She just lay there quietly as basket balls were chaotically landing all around her. Amazing dog.
