I don’t know what cherry eye is. Panus (and I’m sure it’s spelled wrong) is caused by UV rays at high altitudes - generally in German Shepards. It causes blindness. There isn’t any cure but hopefully we’ve got it arrested for awhile. Zuni still have some vision in one eye - we’re hoping Buddy will have some too.
Huh... It’s a new one for me. I sure hope the surgery is successful!
Hope your dog does great with his surgery. They are like family after a little while.
