Dogs with ears that droop like the rottweiler's tend to be more prone to ear infections. You need to keep your rottie's ears clean and sweet-smelling by cleaning them when they're dirty or once a week.
Use a mild otic solution made for cleaning dogs' ears. Avoid solutions with medications and mite treatments as these can cause irritation. If you suspect an infection or mites, have your veterinarian look at your dog's ears. Squeeze a little otic solution into his ears and gently massage them. Use sterile gauze or sponges to wipe out the excess.
Your rottie may have an ear infection or mites if you observe the following:
Ears are foul smelling.
Rottie paws or scratches his ears or shakes his head.
Ears have an excessive red, black, or waxy buildup.
Ears are crusty or red.
If your rottie has any of these symptoms, you should take him to the vet for the appropriate treatment.
