forgive me for contradicting your vet, will you? if you treat it with furazone long term, you are encouraging proud flesh.
caution: vet advice form our vet being regergitated here, probably not perfectly accurately -- and anecdotal story to follow...
our vet taught us about a vietnamese herbal product called Yunnan Bayiao (also a variety of similar spellings). short version? it causes the wound to heal inside outward, not outside-in as a product like furazone does, in theory. in the process, the horse's body breaks down the proud flesh that was previously laid as well.
i'm a BIG skeptic. espeically when it comes to holistic and herbal and such. but had a mare with a horrible gash just above the bulb, and a prior vet who siad "yep, she dun hurt herself" and gave me no advice how to treat it once the proud flesh started. new vet convinced me to wash the injury with filtered water x2 daily, and then pour the powder version of this on it for a week. "if you aren't happy by day 7, then go by the stuff at the feed store, you've lost nothing" was his advice.
By day 5, you couldn't see raw flesh, and the granular proudflesh was gone. by day 15, you couldn't see the wound if you didn't know it ws there.
one more story -- we had a friend's mare have a horrible gash down both hinds legs (tangled in wire) -- university took care of her, sent her home iwth a splint and prescription version of furazone, and prescheduled her for three, yes THREE, debridement surgeries to remove the proud flesh in the next several weeks. (note -- no proud flesh yet when she left hospital.)
Friend is even more skeptical than i was. my vet convinced him to have us alternate -- antibiotic then furazone on day one, yunnan payiao with an aloe cream to hold it in place on day 2, antibiotic day 3, and so on.
when she went to the university for her chekcup and to confirm the first debirdement date, there was no proud flesh and it was healed twice as far along as they'd expected. he didn't take her bakc to the U for any further followup, just had our vet do it (far less cost too!), and you cannot find the scar on one leg, and can only find it on the other b/c it has a solid black line of hair growth.
I've used the stuff on myself as well, for mild to medium cuts, and been very pleased with its results. i buy it online off ebay. comes in tiny bottles, use very small amounts, does an amazing job.
good luck with both injuries...

Yes, that's proudflesh. I just went through this with my guy, after he ripped his chest open and the stitches didn't hold properly. I scrubbed it really well with a stiff brush - until it was bleeding, then I applied Wonderdust every day for about a week. That stuff is amazing! It just ate the proud flesh. We thought he was going to have a big weird bubble because the proudflesh grew on the inside of the flap of hanging skin and we couldn't get to that part very well to scrub it. But it healed up well, and once it was healed over we painted it with DMSO almost daily and now you can't even tell it was there unless you look really close.
Just had some experience with this twice this year. Vet recomended Baking Soda Takes off proud flesh but does not harm healing. Proud flesh will turn black and dry, just pick (hose) it off and reapply. Worked great for both horses I used it on. Did not need anything stronger. And it is cheap.
Definitely proud flesh. My horse had it a few years ago on a gross cut from when he slipped in turn out (on the outside of his fetlock). After treating it for a little while and wrapping it with no improvement I had the vet out. He gave me a steroidal cream (can't remember the name). It cleared it up in about three days. The wound was pretty small (size of a nickel). I would get your vet out to give you something topical to put on it. Treating yourself can be tricky and you run the risk of it getting bigger and more out of control the more you wait.
The best inexpensive treatment I have used on the market for proud flesh with great results is called, Proudsoff. I believe it is less than $12 for a small jar. You use very little and see great results very quickly. GREAT STUFF!
