My godmother, a huge rabbit lover, had told me that Ruby's "double chin" is called a dewlap (spelling?). And it's quite big. She's not spayed even though shes over 2 years old. (She was going to be spayed at 9 months, but problems with weight became an issue). I do plan on getting her spayed but I'm still concerned about her weight. Is her dewlap, or "double chin", a reflection on her weight or diet? Or is it to do with the fact that she's a non-spayed female rabbit?
