Ear Infection Remedies for Pets

I've been using the solution, following exact directions for 5 days now. After the I initial first day of treatment, my dog stopped shaking his head, swiping at his eyes and checking on his paws.

Unfortunately, his ear is now inflamed even more and he's shaking his head again. Last night when I attempted to put the ointment in his ear, he yelped in pain. I will try the garlic and olive oil and hope he gets better or, a trip to vet will be likely.
