Ear Cropping

Cropping your doberman's ears is a personal choice.  If you chose to crop your doberman's ears I have a few recommendations to ensure success.  Gather all the taping and cleaning supplies needed prior to the surgery, work with a vet that is reputible and that can help support you during the taping process.  
I recommend that you join the FaceBook group: Doberman Ear Taping Methods "The Original"  they have great recommendations and resources on posting doberman ears post surgery.
