I found my girl after a week missing, she was outside and the temp got below zero. She can move her toes but her feet are now VERY swollen. They split in one spot but the others just look painful. I would like to do everything I can to help her. Is there a way to release all the pressure? Should I pick up antibiotics tomorrow? She is such a sweet girl and I would hate to just put her down without a chance, but I don't want her to suffer either.
