Pam Houston, Texas 11/18/2014 8:13:48 PM My maltese seemed perfectly healthy until we noticed his ears seemed infected. It turned out to be a yeast type of infection. After treating with antibiotic for 5 days, his hearing was dramatically diminished and he is almost deaf. After reading these comments, I'm convinced that is what happened to him. I stopped giving him vaccines many years ago. Thank goodness I have never had to board him.
