I recently received the following question:-
Hi, I have Clydesdales and have a horrible time trying to worm my mare. Do these extend a fair bit? A warm blood halter can fit my horses.
My response was:-
Thanks for your interest and your question. A good friend of ours used to operate the ‘Horse Drawn in Hahndorf’ (SA) Clydesdales and she uses a Wormabit to assist in worming her horses.
The Wormabit comes with a very generous length strap that enables it to fit all sizes of horses and ponies. The moulding itself is based on a 5 1/2″ bit, and whilst it is snug, larger horses have no problems accepting it. Here is a picture of the Wormabit on her Clydesdale.
