use with caution

I’d give this less stars if able! Used it on my gray horse and within a week he had black scurf all over his body. I assumed it was fungus and got a special shampoo from the vet. When that didn’t work the vet evaluated in person and said it was probably a reaction to the fly spray. Since he tends to be sensitive and has a similar reaction to some lineaments I donated this spray to use on the foals and broodmares at my barn. one day later they all have hives. I

Bronco Gold

This works for at least a day for all my equine. Don't spray in the barn because is smells bad and you don't want it in their food or water. Kills flies on contact which is a little scary too.

Both of my horses broke out into huge hives, swelling in their legs, were absolutely sore to the touch after first application which was barely a mist. One of my horses colicked from the reaction and I had to call my vet!!

a good purchase

I purchased this as you were temporarily out of my trainer's recommended brand. The ingredients are the same as the PRY... brand the formula just isn't as highly concentrated. I found it to work well and feel like it's a bargain. I wish it lasted a little longer, after 24 hrs its time to reapply, but I still consider it a good purchase and will use again in the future.

Allergic Reaction

One of my horses got hives every time I applied. (I stopped as soon as I figured out the pattern.) Other horse was fine. I’ve used other Bronco sprays for years and tried the Gold for the added conditioners. Definitely not better.

Terrible Allergic Skin Reactions

All 5 of my horses broke out in terrible hives after using this product. 3 days later still trying to heal them an I have a show in a few days. Not sure what to do with $40 worth of spray my horses are allergic to. I feel terrible for them especially my yearling and 6 month old. Ages range from 6 mos. to 15 years and all had same reactions. Wish I had done research and seen this common complaint before purchasing. Horses have always done fine with the water based Bronco (white bottle).

Hives Hives Hives!!

Sprayed 5 horses late the other evening for first time with this formula of Bronco. I purchased a gallon. Returned home from work at 6pm following day to find all 5 horses covered in hives . I did some research on reviews all over and found this has happened to many customers. I only hope they dont get the dermatitus and blistering that some have. Pray it's gone before my next barrel race this weekend! Wish I had not spent $$ on a gallon of this stuff.
