Sorry to hear Lady's showing these new behaviors.
I've never had a dog with Canine Dysfunction Syndrom but I think a number of behaviors need to occur to make a definitive diagnosis of CDS. Sending good thoughts for Lady and you.
Here's a website that talks about CDS
Also a Senior Dog Behavior History Form might be helpful.
