Proper Dosing

Appropriate dosing of dewormers requires you to know the weight of your horse. Though a weight tape can help, you may need a more accurate method of determining his body weight, especially if your horse is in any way out of the norm (Warm blood, min, etc.) in size.

Our Weight Calculator takes into account a horse’s age, length and heart girth (barrel), instead of just the heart girth like traditional weight tapes do.

The measurements needed for our Equine Weight Calculator are easy to do – all you need is a soft, flexible tape measure. If you can’t find one that is long enough, use a lunge line or bailing twine to take the measurements!
