Hela needs a new mouth. :'(

Our sweet 7 month old solid black German Shepherd puppy came home missing her lower left mandible and nobody has seen anything like it. Everyone is stumped. I thought she was hit by a car but further investigation at the vets office for our emergency visit said otherwise.
Hela is missing half of her jaw but with no blunt force trauma. They say it's like someone ripped it out of her face... it's missing.. no puncture wounds from a possible other dog. My poor baby Hela girl. They are calling specialists at OU veterinary and Dallas to get opinions and see what can be done to fix her but reconstructive surgery on that scale is very costly. We are not sure of the actual cost yet but figured this is at least a good start. I've never been the type to ask for help but this puppy means the world to me. ❤
