Hot dogs?

Can my 1 year old (who isn't walking yet) eat a whole, raw hot dog? Or would that be considered a choking hazard? I come home from grocery shopping (my mom was watching my baby) and I see my daughter eating a WHOLE cold hot dog, just crawling around and eating it. My mom wasn't even worried/watching. She says that it's fine, but it seems unsafe to me and I am very angry.
