Curious about the dis-coloration with pentosan…My Grey horse gets "stains"on his neck so I changed injection site to hind end.[/QUOTE]
I had three bays that all ended up with weird light colored spots and a change to hair texture in the area where they received pentosan injections (the Wedgewood version). It took probably a year and at least two changes in coat (summer to winter, then winter to summer) for the blemishes to disappear. Since that happened, I’ve read of others here on COTH that had similar spots show up. I’ve been using the HPR stuff on one of the same horses all summer this year and not had that problem.
