Gosh, Vio, I haven't seen you around here for ages. I didn't even know you had moved back to the states.

I think it is pretty early for dementia. Could there be other things? Could it be arthritis pain, and when Pichu stands up, it hurts and it is distracting? Could it be a dental issue? Ears? I am sure you had him completely check over, just mentioning things.

Please, keep us posted.
