Aquitaine has been dealing with this for 16-18 months now. We are still on the Azotemia side of the scale, not crossing over to the Uremia side and I am fighting that tooth and nail. She is on K/D and Purina N/F. She also gets dried liver treats since she has only 5 teeth at this point. She gets some Fresh Pet in her dinner several nights a week. I reached out to the company to check their phosphorous levels since they listed all the other levels on the package and they are within the acceptable range.
Her blood and chem levels have remained remarkably level this whole time. Her albumin is really low. That said, it was low 2 years before she was diagnosed so it does appear that she runs low in that area. I am not downplaying that, it is not a good thing, but until it dips below its long time "normal" rate, I try not to hyperventilate.
She is on a bucket load of supplements as well as some essential oils. Something, everything, we are doing is working. My vet is happy and her specialist commented at her last blood test that he was surprised she was still here. He isn't callous, we had a bad dental emergency in August where she managed to not only get an abscess, but the roots of that tooth wrapped around a vein and she hemmoraghed quite badly and had to have a complicated dental surgery as well as some teeth removed.
I don't know about Renal Advanced or Renal Essentials but I plan to look into them. My girl is on - among other things - COQ10, Fish Oil, Rhemannia, Raspberry Powder, Cranberry Powder (as a preventative), Zantac (following splenectomy 2 years ago), Coconut Oil, Denamarin.
My girl will be 11 in March.
After my initial panic, I did learn that this can be managed. As my vet said when I told him I was going to fight this as hard as possible, we can't cure it but we can hold it back for as long as possible. She doesn't seem to be aware that there is any problem at all so I do my level best to take my cues from her and act as though everything is just as it should be.
