Has Baby had a Thyroid panel done recently? Sometimes the Dodd's panel will find some deficiency that can be addressed with medication. A normal in-clinic T3/4 test will not be sufficient because they may be normal while the rest is out of wack.

I'm not familiar with her history. Is she a rescue? If she came from a breeder that you know, the breeder should have the first option for intervention (most I know, request this in writing). Some rescues actually do take dogs back even if it has been years.
I have never heard of a thyroid panel before. Baby is sort of a rescue.. She was originally bought from a breeder in peachland British Columbia (sunset danes i think?)..Her dogs arnt all registered, or show quality.. She was sold with no papers, under the agreement that she would be a pet dog only. Her original owners couldnt keep her due to moving, so they gave her to us at 3 months old.. Tikeya and her got along great till she turned 2. Thenall hell broke loose.. We spayed her at 6 months, and she was NEVER abused.
I met two of her siblings, both male danes.. They are Both also very dog agressive.. maybe its in the genetics?
