I found the Q and A friday webinar very interesting and enjoy the content. Ear issues were discussed and he question came up as to different treatments and whether the medication may cause deafness. My Gabby, Shar-Pei (think Dorito ears) had some ear problems and at the time I did not know much about alternative treatments. She did have a few treatments with a conventional ear product and she did go mostly deaf. Whether that caused her to go deaf I cannot prove but when I asked my conventional vet, he did wholeheartedly agree that there is nothing else to use and it one of the side effects is deafness. I have since read articles/studies if you will on this. After she went mostly deaf, (she could hear clapping....,) I found out that Zymox could have been used. After Gabby's ear issues were cleared up with the medicine, I did maintain her ear health with Animal Essentials Ear Rinse. Also have read of other things like apple cider vinegar for them. So I wanted to pass my experience along to the person discussing ears. After she went deaf a holistic vet told me to give her Chamomile orallyt which I did but it did nothing . So even for myself I would try and avoid the standard ear preparations out there.
