Dog with a blocked tear duct?

Sara asked:

Since it’s the holiday weekend, I haven’t been able to get a hold of a vet in our area, but i’ve noticed that my dog (3yo female Italian Greyhound) has been scratching and rubbing at her left eye quite a bit. it’s happened before, but it hasn’t been as long-lasting or consistent. Also, her eye leaks and has recently become a little inflamed, but not so swollen that she can’t see out if. i’m going to try to get her an appointment tomorrow or Wednesday when I can take off work, but until then, does anyone have any home remedies or tips for treating it? i’ve tried a warm compress, which she did not enjoy even though it was hardly lukewarm. If anyone has dealt with this issue before, i’d be grateful for any and all advice. Thank you!
