Hi, My horse gets sweaty, with white froth everytime I ride him hard, and I've been washing him on his saddle patch, dock, and mouth, and a little by the reins. I always dry him off a little with a towel, but I can't always get him completely dry, as I only have about fifteen to twenty minutes of grooming him. What should I do, just dry him off straight away without washing or do I wash him and dry him???
