I have a beautiful black and sable 1 1/5 years old and though we brush her, she has developed some thick dreads behind her ears. We take her hiking everyday, so it is not unusual for her to run through streams, bushes and other debris. She has a semi-long coat, therefore the dampness results in knots behind the ears. I have always had smoother coat GSD's, so this is new to me.
I totally understand that there are ways to prevent this, (i.e. brushing her after each hike), but now that the dreads are there I would like to get them out safely.
