I am sorry to hear that. I guess I've missed your other threads about Alzheimer's. Were the signs just like a humans? I remember my chidhood dog, Christy started seeming forgetful towards the last few years. She'd seem to forget who we were at times or where she was. She used to do her circle thing before she layed down, and then do it again like she'd forgotten she'd just done it. I wonder if she had it. My mom never really took our pets to the vet. I'll be praying for Disney. She's such a sweet dog.
