Walter has auper healthy ears inside. He gets them cleaned weekly and has never had an ear infection in his almost two years. However his ears flaps frequently smell sour, like a washcloth that needs washing. I ask if anyone has a tip or product they use to help with this besides a full bath (hes not a big fan and its a lengthy process we do just once a month) the rest of him doesnt have an odor and his sister doesn't have this at all. THANKS!! (Pic of my smelly boy at his latest vet check)
