Why don't you leave them alone and accept her for who she is? You cannot turn a pear into an apple. It doesn't look they will ever stand. She is a beautiful pup. If she does have Beagle (showing in her behavior) in her, work hard in attention for you, keeping her tethered to you for episodes in the day and rewarding her for leaving her nose of the ground while working with her. I don't see any Husky in her.
The advice I got in the way past from a trainer was actually this: "If you want a GSD, get a GSD and not a GSD mix, because you'd be always looking at the GSDs."
It always stuck and it helped me in making decisions on what dog/breed to go for.
Wishing you a good life with her.
