Hi everyone, I know this topic has been discussed before. I'm aware it could be ear infection. Cooper doesn't show any signs of ear irritation, no scratching of the ear or shaking his head. We tried using Zymox ear cleanser but so far the stench is still there. Should I take him to the vet or just wait it out or try another product? Since it doesn't seem to bother him, does that necessarily rule out ear infection? TIA!
