For years my shepherd wore a standard choker chain (modified so it couldn't tighten) to hold his tags, but once I moved into the city with him he was inside a lot more and I also got him micro chipped. He hasn't had a collar on for long periods for about 6 months now but he still has fur damage. He has had several baths during this period. Is it possible the collar line is forever? I'm almost tempted to clip the fur in that area so it can grow back healthy.
