Has anyone ever tried Grapefruit Seed Extract (GSE) for pyoderma? My male cocker has it in his lip folds. And I was told by another cocker owner to clean it daily with a cotton ball soaked in peroxide. However after googling the condition, it appears that he will also need an antibiotic. I'm totally okay with doing that, but I would like to see if there is anything else that might work first. My cocker is prone to having yeast issues and I'm worried that an antibiotic is going to set of a chain of other problems. GSE cures staph and parasites, so I thought it might also work on the pyoderma. I just was wondering if anyone here has ever used GSE on their dog before.
