The other day I used some fly spray that I've been using forever on my other horses, and this one broke out in hives all over. So I stopped using it on this guy, (he lives in a sheet now) but continued using it on the others.
I recently ran out, so bought a new 5 gal jug of the stuff. Mind you, this is the super duper, herbal, citronella, 'good for Dobbin's coat' stuff. While unloading the car, I put it on the asphalt driveway to put groceries away. Somehow, my dog got hold of it, tore the cap off, and the whole thing spilled. I was busy so I didn't clean it up right away. Big mistake. Two days later it had eaten a 10 x 3 x 2 inch hole in the asphalt! And I'm putting this stuff on my horse?!
So now I'm rethinking what I can do for fly control on the poor beasts. Obviously I dilute it before I spray, but still.....
Yikes! I do always spot test if trying a new product because I have had a similiar situation, skin sensitive horse, many things will give him hives.
I have not had any issues with the Absorbine Ultrasheild spray on any of my horses, have you tried that yet?
I have found that just because it says "all natural" that it can't cause a bad reaction, two of my three horses are allergic to anything with tea tree oil in it, and I don't know about horse number 3, since I don't buy any products that have the tea tree oil in it.
