Oh okay. I guess I thought that she was too skinny because those are just full just skin with no fat in them. It's the same thing on the front legs. I am researching what food she needs. Somebody said the curly toenails are a sign of poor nutrition, what do they mean, too much protein, two little protein, etc.? I wish I knew something about her background but I don't so I can just take it from here and try to improve her health.Her back end looks fat to me. Almost like she was fed too much or lots of fatty foods. Either way, I believe it is a girl.
