And if so, what works best?
If a horse has a pink nose (in Australia it is Summer - very hot, so I will definitely need to deal with this right away) does this mean that if exposed to the sun during the day, it will definitely get burned?
I had an old Arab with a blaze and he got burned quite badly if we didn't tend to it by applying zinc; but he got to hating it so much that as soon as he caught site of the tube, he'd run for it. Are there any alternatives that work just as well, if not better, than zinc?
Thanks, in advance!
