I also have Doberman, she loves the Monster 12' sticks. These give me hours of peace. These braided sticks sometimes last days and provide with plenty of me time without being poked by a nose.
I have a doberman and this is the only chew that is safe for her tummy and also gives me about 45 minutes of peace. A MUST HAVE!
We had to give up on rawhide braided rings with our queen-sized Vizsla, Sable, due to occasional seizures. These monster braided bullies give me up to two days' peace and she absolutely loves them! No smell either ... THANK YOU
