This is a great thing to use during the summer!!
In a bottle mix:
1/3 Skin so Soft (from Avon)
You can also add which hazel and other things like that!
The skin so soft is a bug repellent and the mouthwash is an antiseptic that will help with rain rot and other skin problems. And the vinegar makes them shiny and there fur softer! This smells great and the smell stays on the horse too!!
Also when you bathe a horse if you mix vinegar with your soap it helps to make them shiny!!
If you know of anything else like this please post it!!
