Can I use Bottled tears for my dogs Dry eye?

No you can't! If he has a Yellow Discharge coming from his eye, he has an Eye Infection, not Dry Eye. You need to take him to the vet. The vet will put him on Antibiotics to clear the infection up and give him any other medication that the vet thinks he needs. If you don't get this Infection taken care of fast, your dog can lose his sight!
