So far Maggie has improved 90%. She's a shih tzu, 13 yrs old, has allergies, eye issues and meds for that, homemade foods, etc. Had red hot spots, bumps, sores, flaky skin almost all over, it has improved greatly. Downside is she still has some areas of flaky skin, maybe a few bumbs, and licks her areas inside her hine legs. I give her a bath once a week too for skin.
I would recommend Nyzmes, chunk this takes time, be patient.
