I don't see any type of "gunk" in her ear. It appears to be her left ear, but I have been treating both. There is no odor and no visible redness or discharge, and she shows no signs of pain to the touch. The flush and antibiotic is not working long term....I have tried that three times now, and have basically just wasted over $700 over the past few months with no results. We have a Boston Terrier that has bad allergies and we have to give her benadyrl (sp) after she goes outside, so it's not inconceivable that our GSD has a similar issue.
The breeder I purchased from has suggested that I use a cattle/swine parasite vaccine, whose name escapes me right now, and put in her ear. (dosage depending on size). she also uses this as a heartworm preventative, but I don't trust it for that.
I dont want to self diagnose, but her issues are exactly the same as the other times. I live in Alabama and this is not a great place to live if you have allergies, especially this time of the year...... Think I will try another vet visit and get the allergy test and deep ear test done to see what is going on. Maybe that will get me and the vet in the right direction.
Even when she was not having issues, she often shakes her ears. I have not had this issue with any other dog before, but every one is different I guess....
