Thank you for that information. Even though they are touted as digestible treats, rawhids are not. If the dog swallows a large enough piece it can cause an obstruction of the bowel. This will show vomiting , lack of appetite or vomiting shortly after eating, diarrhea or change in stool and lethargy.
Panting can be a sign of pain so that also brings to mind the human food. Some human food is too fatty for dogs, ham, pork, steak, bacon, gravies, etc, and can cause pancreatitis so it is important to know what she ate and if if would be considered fatty.
What you can do is fast her for 24 hours to give her intestine the time they need to become less inflammed. Then feed a bland diet of boiled chicken (no fat, skin ,grease) and cooked white rice. Give only two tablespoons at first and if she holds that down you can give more in 4 hours.
Watch her gum color , capillary refill time and temperature. I will direct you to a site that will tell you how to do this. If any of those are off do not hesitate to see a Vet.
You can also try giving her pepcid now to settle the stomach
