Vet check might be the best thing to do.

Aflatoxin has recently been found in Diamond brands dog foods. So maybe you can rule that out? http://www.diamondpet.com/

Aging can also present itself with endocrine imbalances. Lower thyroid values as dogs age are very common. Sometimes supplementation may help restore confident or otherwise normal behavior.

Also, aging dogs can also have certain forms of dementia -- kind of like Alzheimers. Supplement and change in diet can help this.

Unusual pain or changes in vision can occur as well as a dog ages.

I hope she is feeling better already. Holidays are crazy times for any family member to be ill or uncomfortable.
