No doubt a young dog, and the kill me now comment was based on her face, it looked like she wanted out of life in that picture.
4 years old is super young, that's like a 20 year old in human years.
Any brothers or sisters? if so, I'd pass that info onto the owners so they can keep an eye on their dogs.
I'm not sure, they adopted her from a family up near kendallville when she was 3 weeks old.
