Shih Tzu puppie has Loss of Appetite.  What are some causes?

Sometimes loss of appetite may be due to a pups constipation.  So be observant as to the bowel movements…AT ALL TIMES.
I always suggest taking a look at the consistency of the poop.  Look for blood, or mucus or just simply too hard or too loose.
Then you can talk knowledgeably with your veterinarian when they ask you “how long has the pup had this problem”
Because they will ask you that question.  They will ask for a stool sample.
