2992. A 9-year-old Yorkshire Terrier had creaking jaw sounds and in-and-out tongue movements for a few weeks

Dec 16, 2016

A strange case. The dog behaved normally at the vet as in most patients. No jaw movements, teeth grinding or mobile tongue. Sore eyes and a bald greyish spot below the lower eyelid of the left eye.
"He may be suffering from an early stage of carnassial tooth abscess," the owner thought as she had seen similar symptoms in other dogs with the same condition.

"This is possible as the dog does not permit opening of his mouth," I encountered fully clamped jaws.  

A grey spot below the lower eyelid of the left eye (above).

No loose teeth, bad breath or exposed roots. The cheek teeth were encrusted with golden tartar. "My dog eats only beef, rice, peas and carrots and no dry food, the owner said. "He is allergic to chicken and will never want to eat kibbles".

A well-maintained dog with big eyes.
Blood test. 
Liver disorder. ALT 140 (<59 100="" ast="" br="">Blood glucose low   3.6 (3.9-6.0) although the dog has good appetite. 
Serum urea high 11.7 (4.2-6.3) and creatinine low at 73 (89-177).

Would this dog be suffering from hypoglyacemia, causing the nervous signs of mouth movements?
Also livet disorder could cause acute abdominal pain and hence lip twitching?

This dog loves to lick the floor and other things in the house. So he could have ingested chemicals toxic to the liver. The reaction is nervous signs like jaw movements.
