Massage brush
A massage brush is a flexible rubber brush with nubs that cleans and massages at the same time.

What is it for?
It loosens dirt and loose hair and gives a massaging effect that many horses enjoy.
Where on the horse?
On the muscled areas of the body; softer models can also be used on more sensitive zones.
How do you use it?
In circles with the pressure the horse likes, much like a rubber curry comb.
What to watch for
Adjust the pressure to each horse; even a soft massage brush can be too much on bony or sensitive spots.
Role in the grooming session
Usable at the first step, as a combined cleaning and massaging tool.
