Check her throat to see if a piece of rawhide got stuck. My dog did this and acted the same way. I had to put my hand down her throat to try to get it and as a last resort I made her throw up, which is very dangerous because it can get stuck even more and block airway. I only did it because I worked at a vet before. I would recommend taking yours in.
