Swollen sheath and midline after cleaning
I clean my horse's sheath every year (I use Excalibur) because he is very messy. First time I did that I found that a "bean" was sticking out of his .. and I pulled it - no need to clean rigorously. Yesterday, however, I cleaned him thoroughly. Unfortunately, his sheath was a bit swollen today and his midline as well. He didn't pee so I worry a bit. My friend's horse is better than mine - he peed (his midline is less swollen, just slightly..) . The weather was fine yesterday, sunny with little wind, about 17-20 Celsius degrees.
I could see that his rear was a bit stiff.
He acts normally and eats well.
I am a bit worried. I know he is sensitive to flies that's why I sprayed him against them to see if he is better tomorrow.
Shall I panic ?
Thank you for any pieces of advice.
