Most schools do not allow seeing eye dogs in classrooms either (just on a side note)... Instead, if a student is blind, they attend a special school or have classes in another part of the school with a special instructor that can help them learn despite their visual impairment. Why not simply train the teacher to do what the dog is doing? I mean, how hard can it be to duplicate its behavior and response to the girls' seizures...? It's a dog!
