Can You Use Human Antibiotic Eye Drops On Chihuahuas?

Different antibiotic's work on different thing's so it's not a good idea to use anything that isn't prescribed and your choice may not be safe for your pup. Human and dog med's contain different level's of medication's and it may be too much for your pup among other things (wrong one, side effect's ect.). If it's something like a puncture your risking it becoming infected or other problem's and having to have the eye removed (or popping out or exploding) and it may not do you any good if your baby has something like PRA or detached retina, or some other genetic/congenital/other defect.  If it's something like cherry eye you would be taking the risks but it would have no effect. Best to have it properly diagnosed and get the correct treatment.
