My dog has unilateral ear infection since last night. He is playful, but he keeps scratching his ear. I noticed lots of exudates this morning, and I cleaned them. I wanted to make an appointment but was told that they are not available until tuesday. I have terramycin (oxytetracycline HCl with polymyxin B sulfate) ophthalmic ointment, and put some in his ear. is that okay? also, should I take him to ER?

Place an e-collar (cone) on him to prevent further scratching or rubbing. Use an approved ear cleaner to clean his ears daily. The medication you applied may work if it is a bacterial infection. Dogs can develops yeast infections in their ears as well as bacterial infections. If this is the case, the medication will likely be ineffective.
If you want him examined and diagnosed sooner, you can take him to the veterinary ER. If he is extremely painful, bleeding from the ear, lethargic, develops a wobbly gait or if his ear flap swells, then he should be seen at the ER rather than waiting for your veterinarian.
