Can someone please give me advice on how to train my German Shepherd . She’s had chronic yeasty ear infections since a baby. She’s seven months old now she will not let the vet look in her ears. It’s almost impossible to get drops in her ears. She’s very smart, but very strong willed. She has a lot of bad habits. I’m financially not able to pay for a trainer , but I need help training her. I’m familiar with German Shepherds have had many , but never had this kind of issue.
