What is my dachshund mixed with?

Maggie was running the streets with no collar, some teenager's said she was a stray in their neighborhood Port Huron, MI. This isn't the best photo, but she is 11 pounds, measures 14" long collar to tail, neck is 4" long, front legs 5-6" long, thin & curled up pointed tail, brown paws & chest, big floppy ears, lot's of energy like a puppy, jumps very high and runs fast, very cuddly, lap dog, burrows her nose, snuggles up and sleeps under the covers.
