<p>A lot of smaller breed dogs do tremble and it doesn't necessarily mean that they are cold. Some tremble because they are anxious, stressed, and/or happy. The trembling could be caused by pain or discomfort. She is 13 so arthritis may be an issue. She may not be feeling well. With a decline in appetite my concern is that there may be some changes in her organ function, particularly her kidneys. Hypothyroidism also may be an issue. I do suggest that bloodwork and a urinalysis be run on her especially since she hasn't ever had this done. I would try to take her temperature rectally to see if she has a fever. A normal temperature for a dog is 100-102.5F. If her temperature is higher than this I would be sure to set up an appointment for her to determine where the infection is located. I think the first thing you should do is check her temperature and then I do recommend setting up an appointment with her vet to have a blood profile run. </p><p> </p><p>Please let me know if further assistance is needed.</p><p> </p><p>Theresa </p>
