Can someone please give me some reasons why Kallie's left ear is now down. Her ears have been up since she was a baby and then after she had her puppies last summner, her one ear started falling. It went back up for about a month and now it has been down for a bout 3 months now. The vet thinks I am crazy to care about her ear but I am concerned something could be wrong... Any suggestions??? Any thoughts on why only one would drop???
