Tail chewing?

I suspect another horse is chewing my horse's tail as he is near a yearling. This happened with my old horse and I asked to switch paddocks and it seemed to cause a bit of a fuss. As boarders, do you think it is reasonable expectations to be able to board your horse without getting his/her tail chewed or am I overreacting?

This could be reasonable or not depending on the paddock situation at your barn. Where I board, the horses are all stalled and turned out either in individual or group paddocks. It wouldn't be a big deal to ask to move my horse to a different group, or to get turnout by himself, if I were having a problem with the current setup.

But the way some barns are set up, it would be a bigger deal.

Slather the tail up with dish soap.

McNasty works well.
