Underwood Horse Wound Spray Refill, Topical Horse Wound Care, 16 oz

I can’t say enough about this wound spray. We ended up going through 2 bottles on a wound our horse got. I didn’t know if it would ever heal but this stuff is amazing. We put a layer of the underwood’s on it twice a day and everything is healing up great!

To make long story short, We had just gotten our lil filly when she got hung up in hotwire, we were not there till next morning. Her wounds were devestating. Exactly what you could imagine, down to bone, exposing ligaments and all on on both back legs. This July will be 2 years we will have been dressing them 2-3xdaily. I read about this product in Cowgirl magazine, after checking into the products site, the reviews, and pics from others, the price was low enough that even if it didn't work then that's ok. Well...going into my 3rd month of using this product 2x/day and OMG!!! One leg is completely healed the other has gone from about a 4"x5" opening down to about a 2x2 opening! Not sure what this stuff is but It's Gold to me and I'm Sold! My other horses have had couple scrapes , I spray n powder, and within couple days wound is gone! Keeps the bugs/flies away while healing! I highly recommend this product to anyone with horses. It's very reasonable, very easy to use, and ships quickly but most of all it Works! in the photo above, the first one was after 2 years of still treating it with other dr recommended products and the day we started using this product. Pic 2 is 3months into using this amazing product on both legs , the right leg is finally closed. the left leg has closed quicker in 3 months on this then it has done all year. I will attach photo and how long it took to totally close when it does. We are sold though! its so easy to use and 1 bottle last almost 2 months(if ur not using it on other horses on dog wounds), thats at 2x's daily. I must mention,?you DO NOT CLEAN THIS OFF !! I had to verify that. But you continue to spray more on top of whats on the wound. They stress, when you start using this dont clean off wound before apply new spray , you just spray powder and thats it.

This works great! Every time I have used this the wounds have healed very quickly I have found that putting the baking powder in an old baby powder container helps to puff/ spray the powder on legs/ belly/ chest wounds.

Works wonders

This product is great,would highly recommend it works great on proud flesh

My colt got cut in the fence and this has helped it heal up and keep the flies off of it. I also used baking soda with it. Great value for the money and effective.

Bought this in December 2025 for our horse that got a large laceration on her hind leg. 2 weeks later, it was almost completely healed. 4 weeks later you couldn't even tell she had been injured. This is amazing and we keep it in hand just in case!

This liquid solution does work. However, it’s a mess to deal with. I am using it on the white stockings of my palomino and it has turned the hair completely dark brown and it does NOT come off. I have hosed and shampooed the legs multiple times to get the solution off the hair but it will have to wear off. It must burn a little too because the horse hates getting it sprayed on. I won’t buy it again.

I highly recommend this. Works excellent.
