She was supposed to come with me for Thanksgiving, but I decided to let her stay with my parents instead. Despite me angrily delivering very specific rules they need to follow if they want to be responsible for her, they apparently chose not to listen. They know my dog better than I do, of course. So, they let her out in the morning, without clipping her to her tie-out, and she went for a nice romp in the woods. She is an absolute hardhead and will never show pain, so she came happily bouncing back in like nothing was wrong. She headed upstairs and flopped on my parents' bed, which is when they noticed the rather large amount of blood beginning to pool on their comforter.
I have no idea what she did, and neither do they. They both said they walked back through the woods and couldn't find anything she could have hurt herself on.
On her right hind leg, right below the knee, she ripped the skin off, and also tore some muscle for good measure. It's big. It's about 6 inches horizontally, then another 6 inches vertically. She actually just got the drains taken out.
I'm still pissed at my parents, but I feel so bad for her. I wish I had a magic 'Make It Better' button for her.
