What breed is my dog?

This is my five month old “Chiweenie” puppy. I adopted her from the shelter at two months and was told she could possibly be a Chiweenie. They showed us the mom who looked to be some type of skinny small dog, who they said was a Chihuahua. They had no idea who dad is, but assumed he was a dauschend. I don’t think shes part chihuahua because I feel like her body type doesn’t really suit any type chihuahua, but she could have gotten her dads body type. Any idea what she could be?
