Welcome to the chat! I am Dr. Altman and am happy to answer your questions today
So sorry to hear you are having issues with site and potentially also cognitive changes (disorientation) in Ginger.
Below is more information on this condition, called canine cognitive disorder:
There are treatments for this 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 your dog's 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) is used 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)
6.) Donepezil 10 mg is a newer option used in human Alzheimer’s patients and is receiving attention by some veterinarians for cognitive dysfunction that we see in dogs as well as in humans. The dose ranges from 10-30 mg (1.5 mg/kg average) daily
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
As far as quality of life questions and pain related issues I can give you some handouts to help quantify pain levels. Often we look at quality of life as whether they are still doing any of their favorite things, whether it be a favorite toy or treat, sitting with you while on the couch, barking at the neighbors to name a few. In addition, do they still have the "light" in their eyes (even if non seeing), meaning are they still responsive to their environment and you or are they dull, listless, and fading away?
