14 year old Cavapoo with Cognitive Canine Disorder

Hello! My mom is 81 one and her cavapoo is 14. Dad picked her out and he passed 4 years ago. Mom has moved into a retirement facility October 2025 which is her own 1200 sqft apartment from their lifelong residence. She started displaying the CCD around June 2025. She has seemed to adapt well to the apartment but recently she will bark non stop the entire time we are gone for a doctor appointment. She is on a med from the vet that she takes each morning and that helps her somewhat be herself. When I have to take mom to an appointment she will start pacing and will bark entire time we are gone which does not work well in a community setting. We set up a doggie cam and have seen this behaviour. Any ideas on how to stop this?

She is also becoming increasingly difficult to feed. This dog does not eat kibble. She gets cooked chicken breast, peas, ground turkey, scrambled eggs, etc. We have supplemented with the Little Ceasars wet dog food also. She has to take her med in the morning as it does calm her and there have been times we have had to mix her chicken with the med in a small amount of ice cream lol. Pretty much anymore we have to take her bowl to the recliner and start to hand feed her and she will then start eating out of the bowl. Last month she just ate out of her bowl on the floor like normal but has since reverted. Many times if she sees you with her food she will run away from mom. I can catch her but mom can't.

Any ideas would be appreciated as this is also very stressful on mom who is also having health issues.
