@boomerang,
So now here is some chick on a message baord.
If it is an allergic reaction to pollen, another dogs soap, dust, dirt who knows..
basic saline eye drops would help him with his rubbing.
If you have some, give it a shot.
Saline is perfectly safe water. It will help relieve itching and irritation, and as a side it will help irrigate the eye.
I do not think this would constitute an emergency vet visit.
Not when you can schedule a regular visit for monday or tuesday.
