Hi everyone! My almost one year old australorp got her leg stuck on a piece of string that was in our yard. I don't know how long it was stuck for. I was taking my dog out to use the bathroom earlier and I thought she was just laying there. I came out twice and my sister said she had a string stuck to her leg. She didn't have any cuts or swelling. She tries not to put pressure on it but can walk on it a little. She can walk on it and use it. When she was there she didn't make any sounds of distress or pain. When I touched it she didn't resist so I don't think there is pain when I touch it. Is it sore or sprained? Should I just let it heal on its own? Thank you in advance
