About 8 hours ago, I hear what sounded like Lucy getting into badness from the other room and sent my son to check. She'd gotten my Happy Eye Pillow, a little silk pillow filled with flaxseeds and torn it open. She ate a bunch of the seeds. Now I have scoured the internet and couldn't find anything that said flaxseed is bad for dogs, just the opposite - a lot of advice to add it to their food - so I think what happened next has to do more with her brain than the flaxseed. The seed made her stomach upset and she threw up several times. She seemed fine for a few minutes, and then she had a partial seizure. Every time I tried to move her she'd start seizuring again. The the seizures stopped and she was comatose. She didn't react to any stimuli at all, not even a hard toe pinch. My husband is out of town with the car so I had no way to get her to the ER vet, but it looked pretty hopeless anyway.
I tucked her into bed with me and just held her for a few hours. I slept for a bit, and she was still with us when I woke up three and half hours ago. I picked her up and put her on her comfy cushion, resting her head on her favorite plush toys and covered her with the blanket she liked to steal from me. I checked on her every few minutes while I searched the internet for any advise, any hope. Finally her breathing became loud and irregular. I snatched her up in my arms and I could feel her heart beating so fast under my hand. Her entire body was limp except for her front legs, which were very stiff. And then they suddenly weren't stiff anymore. I couldn't feel her heart anymore. She took a few more ragged breaths, then her bodily functions let go, and she was gone...
I'm just devastated. My whole family is. We knew we were on borrowed time - they told us that the sudden development of seizures in an older dog was almost surely a brain tumor or some type an aneurysm, and not treatable. But I can't bear it that she's gone.

This is Lucy Jo when she was just a few years old. Good night my beautiful princess. I will miss you forever.
