How I Began My Research.
Bottom line: no one knows what works. No one knows if anything works. We're all part of a giant, collective science experiment.
I expect to continually tweak this over time as I gather more information.
In every meal I include veggie mash. I used to make it by putting the veggies through my juicer and adding pulp back, but now I make it using my fabulous Vitamix. Worth every penny. The mash includes carrots, spinach, parsley, dark leafy greens, broccoli, and blueberries. I make it in batches and freeze it in ice cube trays. Dogs can't extract the nutrients from raw veggies (they can't digest cellulose), so you either have to cook veggies or pulverize/juice them to break down the cell walls.
Prozyme. I used to mix this into Trevor's food since digestion (lack of absorption) is suspected to be a contributing factor with RP/PRA. However, he didn't tolerate it well even in fractional doses, so I've discontinued it. Still, it's worth considering.
In December 2009 I made some major changes. This was largely driven by the fact that at long last, an eye supplement designed for dogs came on the market. It's called OcuGLO. From the OcuGLO website (I believe this text has since been taken down):
We are very excited about Ocu-GLO Rx Vision Supplement for dogs! We conducted a one-year-long clinical trial on our patients in Washington and Florida in 2007/2008 and we have seen wonderful results, especially in patients with retinal degeneration. Please keep in mind, however, that the goal of this nutraceutical is not to cure anything—it is to help lessen ocular damage caused by disease and hopefully “buy some time” in which your pet still has functional vision.This is exciting, because it's a validation of what I have been trying to do with Trevor on my own over the last year. But whereas I was often taking my best guess as to supplements and dosages, OcuGLO is formulated specifically for dogs, and there is some science behind it.
Here is some more information about OcuGLO from the Animal Eye Care clinic website.
Because OcuGLO is a multi-ingredient product, it overlaps with many of things I was giving Trevor before. This required me to drop some supplements I was using previously.
Low carb diet. Sugar is also an oxidizing agent.
