Yup its ok. I crave chili dogs all the time lol
As long as the hot dog is heated to the right temp you'll be just fine. I had chili cheese dogs the night I went into labor with my 2nd I'm pregnant with my 3rd.
You can eat hot dogs but I wouldn't consume too much! Hot dogs have nitrates in them! When I was pregnant with my second if I smelled or touched a hot dog I would vomit!
Nope, go for it! You might get heartburn lol
