The difference between White Line covers and jute is mostly it's softness.
It is more comfortable for the dog than jute, it is therefore
especially valuable for puppy foundation work, and for working on power
striking techniques with young and adult dogs.
It is a bit more durable as well, we usually say it lasts about 15% more time that jute.
Another advantage is that it is not a 100% natural fiber like jute is,
and so it doesn't suffer from being wet then dried as jute does, and
requires less storage storage care.
