I think it helps too because as well as keeping the eye open, gentle ear pulling is a piggy whispering friendly dominance behaviour, it says "trust me I'm the herd boss"Ooh I like the ear trick.
I didn’t like using contacts so wouldn’t feel too confident applying with a finger! I’ll have a bribe at the ready.My vet suggested putting a drop on my finger ( gloved), and gently administer the eye drop that way.
It worked with Micah who would close his eyes tightly as soon as the dropper came anywhere near.
A bribe is also essential
