My Vet has given Chester these drops and I noticed when I got home that they expired May 2004 16 months ago: Will they harm him in any way? I am terribly worried especially given his age (for a Dane).



Dear Kate,
If stored in correct conditions, the drops should still have some activity: you should see a response to them when you put them in the eye. however, you should inform your own vets - and no, they will not harm.
