She's barely a medium dog. She's 6 months old and around 16-18 pounds (might be around 30 fully grown). She's lean, not really skinny or chubby. She's a dachshund mix, we think she might have some kind of hunting breed in her. Someone mentioned basset because of her feet but she definitely has something else in her if so because she's way leaner than a typical dachsund or basset.. and maybe too tall to be part beagle like the shelter guy told us? She's the size of an adult beagle if not a tid bit taller; my grandpa had a couple beagles when i was younger he used for hunting rabbits.
I'll increase her from 1 1/2 to 2 cups and see how that goes.
The picture below is from a month ago but it's hard to take a picture of her standing from the side.
