dogs with sore jaws keeping them from eating

Question
I have a 12 year old shepherd/husky mix (about 40lbs)
she is healthy and active but recently is in pain if she opens her mouth to eat dry food.  What can cause this?  Other symptom may be she is shaking (not bad, but it is out of sorts for her)

Thank you,
LaNita

Answer
The shaking is most likely a pain reaction. She needs to be seen by a veterinarian to determine if this is from bad teeth that need to be pulled or if she may have a dislocated jaw... or even some other issue.

Personally, I would take her to a veterinary chiropractor, as that would be the best person to determine her problem. http://www.avcadoctors.com/search_for_avca_certified_doctor.htm
