Hello. I've got a 10-week-old rough collie male headed home with me next weekend. I'm new to the breed and am curious if anyone here has suggestions for collars/leads: Both for a new puppy, and then for an older dog for later. I'm concerned about regular (cheap) collars of all types ruining the fur around the pup's collar. Anyone have any suggestions or experience to share? I would plan to leave a collar on the dog at all times in house, so would a rolled leather collar with his ID tags work for both that and for walks/training? thanks in advance. -tp
