[NAGDU] training philosophies

[Jean Menzies]

Hello all, 

I figure there are folks here who would know the answer to this question. I know many of the schools use positive training methods and rely heavily on treats as part of training. I am wondering if various schools use treats more or less than others. I seem to have it in my head that the Seeing Eye uses treats only for target training, and uses more verbal and physical praise for general work/training. Is that true? Just curious. 

Thanks. 

Jean
