I have 7 year old alpine wether that has recently started dripping urine. He doesn't strain whilst urinating and shows absolutely no sign of discomfort. He urinates normally as well, he just drips in between. It's not constant, I'd say 1 or 2 drops a minute? He's on 70 acres of pine/native grass/shrubs and that's pretty much all he gets in the summer. I supplement with hay in the winter. He gets free choice mineral. Any ideas? Should I be worried or is more like urinary incontinence in spayed female dogs?
