Sorry it took so long to respond. I have a lot going on with spring and drier weather. From what I can gather it must have been a brain tumor/cyst. A couple days before I noticed her eyes were bulgy, I took a pic and sent it to my mom, she agreed her eyes were not normal. So we made plans to get her the vet, she didn't make it to the appt. One minute she was here playing and the next she was on the ground violently shaking (I'm guessing seizure) then she was gone. My mom was talking about it at work, a co-worker of hers was dog sitting when a similar event happened with the dog, the vet said a bursted brain cyst. Lulu aged quite a bit and had some big behavior changes over the last year and half, I presumed it was all stress, the timing for everything (and her history) was perfect for stress to be blamed. But in light of this. I wonder. Or maybe all of this could be blamed on the stress. Who knows.
Thank you for all the kind words, it helps. Losing Lulu has been real tough.
