I don't mean to scare you, but I did a search on bloating and drooling and if she has bloat, it is an extremely serious condition and she should be seen by a vet asap.
The symptoms seem the same, but you said she's had this bloating for 2 weeks? If so, I don't think that's what she has, but I could be wrong. I still think she should be seen. She must be very uncomfortable and probably in pain since she's passing very smelly gas.
Here's a link to Bloat in dogs.

Sending get well wishes and keep us updated on how she's doing!
