I have a 15 year old sheltie who has stop eating for almost two weeks. I gave her can food once and she ate that. She did eat two dental treats. She does pee and has loose stools. Her eyes look droopy. This started after being boarded for a week. Thoughts

Poor Nellie! Not eating for two weeks is a serious problem, so I would recommend taking her to the vet today. She should have a thorough physical exam as well as blood work or other testing if needed to help determine what's wrong. Some common possibilities in an older dog like this would be liver or kidney disease, thyroid problems, or even some type of cancer.
