Rolled leather if you must use a collar.

My dogs do not wear them at home. They will chew leather collars off of each other, and the fur-saver is likely to get the links stuck on things (such as the top of a chain link gate when the dog jumps up to see what is on the other side).

Any collar with tags is likely to get the tags hung on things. Floor vent grates are particularly dangerous. The round ends of chain collars will also hang up in the floor vents.
