Ein is a Pembroke Welsh Corgi whose insights was extraordinarily improved by an exploration office. Ein is known as an "information puppy." What precisely was carried out to expand his sagacity is obscure.
Notwithstanding Ein's improved sagacity, he stays unequipped for talking (other than yapping). As a result of this, his discernment generally goes unnoticed. It does appear that Ed comprehends Ein through his non-verbal communication and yelping, however this is never made unequivocal. Ein likewise barks once for yes and twice for no.
