I think it may be a tooth,but the Dr.
disagrees. Regardless of what it may be, how do I
get her to eat?
Animals do not suddenly stop eating unless something is wrong. To get your dog eating again, you need to find out what is wrong and correct it if possible.
A very large number of diseases and syndromes may cause a seven-year-old pet to lose its appetite. Many, such as kidney disease, bladder infections and advanced diabetes, are detectable on basic blood and urine tests. Others, including certain intestinal disorders, foreign objects in the intestines and most forms of cancer, are not.
I think your dog needs more tests. I would recommend X-rays and ultrasound of the abdomen as the next step.
Dental problems cause pets to lose their appetites rarely. However, if a thorough diagnostic evaluation fails to determine what’s going on, you may want to consider dental work.
