Hi Linda, Both my Berners (Daisy and Buddy) are used to noises since I made it a habit to drop objects, etc. during their puppyhood. I bought two bells (small and medium) from the Care-A-Lot Pets catalog. They are not as loud as the Swiss bells. I think I could have hung the Liberty Bell from their collar and they would not have hesitated because they love to go for walks. I remember them looking at me with confusion when the bells first jangled but I just clapped, jumped up and down and then gave them a treat. The smaller bell makes a low tinkling sound -- just enough for me to figure out where Daisy is in the woods.
I'd try a smaller bell, put it on your Berner, let it jangle, cheer, give your Berner a treat and immediately remove the collar and bell. Do this several times extending the time the collar/bell is worn. I'm sure the Berner-L pros will have some good ideas. Good luck! Maria Crifasi Catoctin Mountains, Maryland
