I ordered some Canvas Bumpers for my 12 year old girl to play with because she still loves to retrieve. . Now the 5 year old golden female who never showed any interest in retrieving is picking them up and returning them to me on land and water. She will take a plastic bumper in the water. She only will put the soft bumpers in her mouth. I just thought this to be very strange but the soft Dokken ones are more like the real birds than plastic. Has anyone ever seen something this any of the retrievers?? I just thought it so bizzare that all the sudden that this happened.
