A few weeks ago I noticed my 20 year old gelding’s sheath looked a little swollen. I gave him a good cleaning, he only had one tiny bean, but a lot of slimy, goopy smegma. Swelling went down and he seemed to be better.
Noticed the past couple of days it started to swell again, so I went to inspect and clean it today and his entire sheath is just covered in slimy smegma. Not like the flaky pieces you can pull off, like each time I stuck a sponge up there it was covered in smelly gray slime.
Vet is coming out anyway for spring shots, so I’ll have her look, but just for my knowledge could it be infected? What would cause that?
