Neatly Trim Your Horse's Tail

youll need
Mane comb
Sharp scissors
A plastic bottle or cardboard tube about 4 in10cm in diameter optional.
Or in place of a tube or bottle an assistant who will lend an arm optional.
Your horse should be accustomed to being groomed and handled and be calm when you work around its hindquarters. Follow these instructions to bang your horses tail
Brush the tail smooth. Dont wet it. Grooming sprays and detanglers may make it harder to keep the scissors steady for a straight clean clip because they make the hair more slippery.
Have your assistant place the bottle sideways beneath the base of horses tail so that

it lifts the tail more or less into the position it would be if the horse were moving. If your horse isnt going to squirm it might be relaxed enough to hold the bottle in place on its own. Alternatively you could just hold the tail up with your arm but this is more work and you could easily move your arm without realizing it. An assistant can be helpful to either cut or hold the tail up.
Grasp the bottommost portion of the tail and hold it into a tight bundle. Cut straight across the tail hairs. When the tail is dropped bottle tube or arm removed the cut ends of the tail will be at a slight angle to the groundthe front being slightly shorter than the back. The cut will now be square to the ground when the horse is moving.
As your horses tail grows the tail will have to be trimmed again. How often will depend on how quickly the hairs grow.
