Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
So sorry to hear Paige is having some senior issues. First, I want to ensure that metabolic causes of her increased hunger has been ruled out. Has your vet run basic bloodwork to ensure there are no possibilities of Cushing's disease (CLICK HERE)?
There are treatments for senior cognitive changes that can help in supplement form but also in some situations medications as well.
1.) Melatonin can help with barking or increased movement at night
2.) Proneurozone which is a supplement for brain function that can help with mental clarify in senior pets. It is available through your veterinarian but also on-line at stores like amazon.com
3.) Fish oil is essential for brain function and used at higher doses to help cognitive function. For example, for his size 1000 mg EPA & DHA daily. This can be a human formula
4.) Anipryl which is a medication used for cognitive function if the above options are not helping
5.) Alprazolam (xanax) which you are already using for episodes of anxiety not controlled by conventional methods. Not intended for daily use but is effective as needed (in the diazepam or valium family)
These are all methods that your veterinarian would have available to you to assist with some of the cognitive issues and some that you should be able to purchase at a local vitamin store or on-line
I hope the above options are helpful to you but if I can assist with clarifying anything or guiding any further questions you might have please don't hesitate to ask.
