Okay, folks -- this is even hard for me to write ... am afraid that Maggie is starting to show signs of dementia. She has times when she seems very disoriented -- just sitting staring into space. When I take her outside to pee/poop, she often doesn't know why she is outside. She has also shifted from always being very particular to where she goes on the grass to peeing/pooping on the sidewalk. It's not that she is doing either urgently and just not making it to the grass. At one point last night she seemed like she didn't recognize me. She is not on any new meds or food and nothing else has changed in her environment. I will talk with the vet about this next week but just wondered if any of you with senior pups have seen similar changes.
