I sprayed bush kill as my dog ran by and she got it in her eyes. I rinsed and rinsed, but after 12 hours they were bright red so went to the vet. She looked carefully and said I might want to use some ointment $10.00. Her eyes were fine within anothe 24 hours.
Read the label carefully, it should say how long to keep the pets/children out. I think it says until it dries or something. It should also say what to do if they exhibit symptoms, and what symptoms to look for. Usually the bottle has a peel-open book attached under the label.
I know what you mean about never again! Hopefully there's no harm done.
Save a life, Spay a pet!
