A.A case like this should really be treated hands on by a veterinarian. I would recommend finding one well versed in integrative medicine. With that being said, I will list here several of the supplements used in my facility for what you describe. Doctor’s Mutual Service has a relatively new supplement called Kidney/Heart. Taurine, vitamin E and CoQ10 would also be indicated. And, if this is a heart condition involving a dilated heart muscle, then you could add l-carnitine. In Chinese philosophy, there is a correlation between the kidneys and the ears. I’m more in favor of higher quality foods than the more processed, lower quality ones.
