1st just let me say a very big Happy Birthday to Chico. I am so sorry to hear that both pups are having such serious ear issues. I hope the meds work well and that they both clear up soon. Sending lots of love to them both!!
On a side note I know some chronic ear issues can be caused by genetics, but not in all cases. Mr. Moose has chronic issues with his ears that require daily cleanings, and medication that contains an anti-inflamatory and antibiotic. He will be getting them for the rest of his life. I have seen all of his brothers and sisters (from 4 litters) and none of them suffer from the same issue. I am not saying that the breeder should not have disclosed the fact that there were genetic issues in the breeding lines because she absolutely should have...I am just saying the ear issues may be an entirely seperate issue...especially when both Chico and Kody (who had been fine) now have the same problem.
