My daughter and I spent over an hour bathing our horses yesterday. Her little mare is a perlino Paso Fino - almost but not quite white. She was really filthy. I gave my poor DJ a bath. He's a tovero paint, very light colored with pink skin. I don't get to see a lot of him up close and personal - it's dark when I leave for work in the morning and almost dark when I get back home. Didn't realize my poor guy was so sunburned!
I thought he had stuck his face somewhere it didn't belong, but the farrier was out yesterday and said it was sunburn. Hence the bath. I genthly but thoroughly scrubbed him all over, including his face. Put a little anibiotic ointment on raw spots, then sunscreen on all the light colored areas on his face and back. Sprayed him thoroughly for flies (he's a horse fly magnet! I swear he has a sign on his shoulders that says free lunch!) and put him back in the pasture. First thing he did was head for his favorite dust waller! It really stuck to him, too, because of all the goop I put on him. He looked awful, but seemed much more comfortable. I thought about a fly sheet for him, but since he's a pasture pony, I think it would just get caught on something and really cause more problems than it solves.
Daughter's horse loved her bath. She has darkish skin, thus no sunburn, a for some reason, the flies don't bother her much. (Maybe the flies are more interested in DJ, so they stay down in the pasture?) However, the first thing she did after her bath was roll in her favorite waller. She looked worse after the bath and roll than she did before her bath. But, the mare is happy, even if daughter isn't!
