Vetoquinol is a company that carries medications that are used in dogs that have kidney disease/failure. One of the most common products is Azodyl.
Is Rocky on this medication?
Why are you looking to put Rocky on an antibiotic?
Thank you for the information.
Unfortunately there is no other medication to resolve a cherry eye. A cherry eye is where a physical portion of the eye (this is a gland) luxates out of place. Because of this, to resolve it, the gland actually has to be physically put back in place. The good news is, that once it is replaced, dogs tend to do wonderful!

You can certainly get some more of the medication and continue to try, but likely you will need surgery to replace the prolapsed gland. Even with getting it back in place, eventually it will prolapse again at some point and continue to do so until it is sutured back in place.
