Late last fall I caught Dante peeing and his urine flow was really dark and nasty. I worried because having a brown urine (excreting proteins) could have been a sign that things were going south with his PSSM. He hadn’t tied up with me but I was worried we were one step away from that happening; and as it is, I suspect the stifle injury was the result of these tight muscles.
Happy to report that I got to see him pee today and it was a nice light, sunshiney yellow! Yay! For Dante!
