We think she had a stroke some time between Monday night and Tuesday morning. She was worse last night when I got home, had a hard time keeping her feet under her and just basically zoned out. She was a little better this morning mobility-wise and when I checked on her at lunch she's gotten a tiny bit more of her personality back. But overall, it's like about 90% of my dog is just gone. She goes through the motions like she knows she's supposed to be doing this things -- eating, expelling waste, sleeping -- but she doesn't remember why. Hopefully she will continue to improve but unless it's a dramatic improvement I won't leave her like that with no quality of life.
Some hard decisions to make in the next several days.
