Thankfully my vet is good about communicating via text. Had a cow last summer with what I though was pink eye. I was treating her with terramycin and it wasn't improving. We got her in the squeeze and sent pics to the vet. She said most likely foreign object in the eye. She told me to glove up, get some lube, and sweep my finger into her eye lid (she also said don't worry about going deep - eek). But after doing that I picked out a fox tail. I think the more things you encounter the more comfortable you get doing it.
I also just learned how to draw blood to send off for preg check. Super neat but I may need some practice before mastering it.
