Sagira has a boo boo

We were outside cleaning up dog poop since the snow has finally melted. Sagira was running and playing like any normal day. She was extremely muddy though since the yard was so soft. We look at her and notice that she is bleeding under her eye. It looks like she scraped herself on something and tore off her fur and about 5 layers of skin. We immediately stopped what we were doing. Took her in and bathed her. We put some peroxide on the area and put some neosporin on it. I hope it doesn't leave a horrible scar. I feel so bad that this happened and don't even know what she did to cause it. :(
