It's getting a ton of use at my place right now!
My horse has a minor fungal infection in her left ear, we cleaned it out with betadine, tried some cream on it which did nothing and now the Vetricyn is really clearing it up. Cleared up her right ear immediately (very small infection in that compared to the left). It's a spray bottle, so we spray it on a rag and then wipe it on the inside of her ear.
The other horse scraped/cut the heck out of her leg throwing a tantrum going through a gate, sprayed it on after cleaning and it cleared that up.
A friend's dog was visiting for a week, had a huge bare spot on it's rear that the owner said he'd "tried everything" on, so for the heck of it we tried Vetricyn on it, since we had a bottle for the horses and the bottle said it was safe to use on dogs. The dog was regrowing hair by the end of the week and it's perfectly fine now.
So, I'm happy with it so far!
