What it is:

pancreatitis is where digestive enzymes are released early (in the pancreas) as a result of too much fatty food. In other words, the pancreas is being digested.

Symptoms include:

lethargy
nausea
diarrhea
abnormal eating/drinking habits
panting in room temperature (72 degree) environments

What you need to do:

if you suspect pancreatitis, it's relatively common in Yorkies. Ask your vet to check the pancreas area for swelling. If you feel concerned, ask for bloodwork to be done.
You also need to immediately cut back on common fatty foods such as cheese.
