What happens if a dog gets human eye drops?

A dog getting human eye drops may cause the following problems. First, some ingredients in human eye drops may be unsafe for dogs and can cause allergies or other adverse reactions, and in severe cases can even lead to blindness. Second, the dosage of human eye drops is designed for adults and may be too high for a dog; an inaccurate dose can cause adverse reactions such as excessive eye irritation, redness, and pain.

Finally, although some human eye drops are indeed safe for dogs, they may not match the actual problem, so they may not resolve the dog’s eye symptoms.
