Answer
Dogs get many kinds of throat irritations just like we do. They get infections in their chests and in their trachea's too. When a dog gags and hacks like that there is sometimes something stuck in one of their tonsils.
Most dogs will cough until they vomit and if they are vomiting hard enough they sometimes can vomit up from deep in the stomach which could have some digested food that will smell awful like stool.

You need to take her in to see the vet. He/She may need to prescribe some anti-inflammatories for her and some antibiotics.
He/she may also need to look down her throat and may have to give her a sedative for that.
I am sure she will be fine but she does need to be seen soon.
