Hi Nici
My dog wasn't a Shar Pei, but had chronic renal failure, and trying to go beyond the two weeks they gave her, I came across the website which is written about kidney diets, for her Shar Pei who has Shar Pei fever, and at 14 years went into kidney failure. I don't know of the drug, but it is mentioned on the weblink that someone else posted, and so I believe if it were me I would try it, especially if you have read of others who have used it to good effect.
If FSF can be diagnosed by blood test, most definitely have it. The more you know, the more you can do about it, at least, that's the way I am. They can also use the same blood to check current kidney function. When I was monitoring Elsa for her kidney function, they got used to me waiting for the results of the test, which usually took about 10 minutes, and with the help of that website, I got very good at understanding them. The diet food that they gave me for my old girl was a kidney diet (low protein, high fat) to try and help, but at the stage she was at even that was too much for her. You must remember here that my dog was in end-stage renal failure, ie less than one third total kidney function left! So then I came across the website I posted up (can't do links, so you have to copy it and paste it in your browser) the lady that created the site has the Shar Pei, that is finally having kidney problems. I fed my girl a home cooked diet, created from what I learned on her site. You see, by then I had nothing to lose! My vet has since asked me to pass it on to someone else whose dog has kidney failure, as they know that we did so well.
If kidney disease/dysfunction is spotted early, the prescription low protein diets work wonders, and preserve the kidney function. Unfortunately, general renal failure is not apparent, until they start vomiting/being lethargic, and so often by then the damage is far advanced, as in our case. If I had found out about it 6 months earlier, I know we could have had a lot longer, but that's the way it goes. In your case however, you are forewarned that kidney problems may arise, and so can monitor regularly and take the appropriate action when the tests show any deterioration. I haven't heard of they food you mention, we had a k/d prescription diet. However, there is no point in changing diet until her kidneys change, because there is no evidence to suggest diet can prevent kidney problems, only alleviate and help once it happens. One thing you really must avoid is cod liver oil/Vitamin A. Use Omega 3 fish oils if you wish to supplement with any fish oil, but not cod liver oil.
I'm glad you're feeling better today, and hope I have helped (hope I didn't misrepresent myself though, not having a Shar Pei!). Where kidney problems are involved I always dive in, and try and share what helped me so much.
It was a year ago yesterday that I lost Elsa, and I have posted under rainbow bridge 'A Year ago today', so thank you for your message.
