She's not going to be big enough for coonhound and probably not even whippet. I wouldn't put chihuahua past her. The tail and the button ears are her only for sure non-beagle feature. I would say beagle with pug or chuhuahua or with chug (pug/chihuahua mix). And no, not all beagle pug mixes have smooshed faces or black and fawn coats. Mixes can vary in any degree for looks including 99% looking like the mom or dad and anything inbetween.
