What happens if your dog eats contacts?

Answer 1

They'll think "ew, that tasted weird". And then pass it out the other end about 24 hours later.

No known health complications from dogs eating contact lenses have been recorded. The saline that contacts are kept in is just salty water with enzymes in it. Give your dog some fresh water to get rid of the thirst caused by the salt in the saline. He or she will be fine.
