Our Nubian buck has been lame on his hind right leg for a couple weeks now. We thought it was his hooves as he probably hasn’t had them trimmed in his life. We built a milk stand and trimmed them and he’s still limping. I put him in the stand a week later and trimmed them again but that didn’t seem to help. Some days he’s limping just a little and others the limp is bad. Any thoughts?
