Hi all -- I know some of you have mentioned using arnica topically on does that have had a rough time kidding. I have used an equine product -- Sore No More -- on my horses before, and recently on me. I have a knee that swells and gets really painful and the SNM really helps. It's unbelievable how well it works. It's a combo of arnica, rosemary, lavender and lobelia. So here's my question. I have an older dog with arthritis in both stifles. I've started applying it to her, and it seems to help. Do any of you know if I can find a stronger arnica product, how to apply it, and how often? Thanks!
