Welcome to Calm Healthy Horses

The purpose of this website is to help solve the frustrating, expensive, not to mention painful for the horse, problems that plague so many horse owners world-wide. Problems which seriously impact your safety, enjoyment, sanity, stress levels and your wallet!

Don’t waste time, energy, money and precious horses battling ‘issues’ that simply disappear when you get the diet right.
There are some Dietary Principles to understand and follow. The underlying explanations lie within the mind-bending world of bio-chemistry but don’t worry you don’t have to become an expert in that subject in order to help your horse!

Step one is to Download and print off the HEALTH CHECK and the CURRENT DIET REVIEW.
Step Two is to go to SOLUTIONS and read Dietary Principles for a Calm, Healthy Horse

To avoid injury, also read ‘Don’t ride if…

You will be amazed at how many issues are actually diet related. Whilst ‘diet’ encompasses everything your horse consumes the problems usually originate from his pasture grass. Hence, the term “Grass-Affected”. Meaning there is one or multiple aspects of your horse’s forage and feed that is adversely affecting his health and behaviour.

Is your horse Grass Affected?



Some people don't even realise their horses are Grass Affected until it is too late and either they have a nasty accident or the horse becomes unrideable due to Head-Flicking or Laminitis.

The thing is that in most cases the symptoms occur long before the horses get to this stage - we are helping you to recognise the first signs and how to correct the horses diet immediately you notice any changes in the horse.
In the mean time, visit our extremely informative website, which is being constantly updated with the latest research. We too continue on this journey of learning.

Despite their owners spending vast amounts of money on professional advice, thousands and thousands of horses and ponies all over the planet succumb to a wide array of serious health and behaviour problems every year.

Thousands are put down, turned out, sold for the wrong reasons, don’t reach their full performance potential or are retired far too early.

Thousands become metabolic, get laminitis, are diagnosed with ‘sacroiliac’ problems, become head-flickers/shakers, get mysterious bouts of colic, allergies and skin conditions or mud-fever, buck or spook people off, are forever needing therapies and treatments for ‘muscle-soreness’ or have endless trouble with saddle-fitting.

Ever more horses become over-reactive and therefore dangerous. The combination of an over-reactive horse with a person who does not ‘read’ these signs is a recipe for a serious accident.

The emotional toll on their owners is significant. If your horse isn’t right it ruins your whole day. The economic toll can strain relationships because the non-horsey half doesn’t understand.
Desperate owners spend significant amounts of money on every treatment known to mankind. They spend it on everything except the ‘one thing’ that will make the most difference: their grass and its proper management.

About Us

We specialise in 'Grass Affected' Horses.

That means we know this syndrome inside out, in fact it was Jenny who first recognised and coined the phrase 'Grass Affected' over ten years ago.
So how did this come about?
For fifteen years, Jenny was a Horsemanship instructor teaching all over NZ.
In those days many people arrived at lessons with all manner of problem horses.
She often had many students return again and again and the same problems kept rearing their head, despite the fact that they seemed to have been sorted in the lesson.
Problems such as running off, being extra spooky, head-shy, aggressive, girthy, tight behind so unable to canter properly - swapping leads, 'bunny-hopping' with the back legs together. These are but a few examples from a very long list.
It became clear that it was nothing that the students themselves were doing wrong, and many of the students had also spent big money on excellent professional help encompassing every treatment known to mankind but still without satisfactory outcomes.

Jenny started to notice her own horses would have problems when they grazed certain types of grass. At first, she thought it was a purely mycotoxin problem but realised after a few more light bulb moments that there were other more important aspects of the pasture grass causing these issues besides toxins.
She took on some 'seriously affected' horses and deliberately did nothing else but change their diet. Within a month or six weeks they would be completely back to normal without having done any 'work' on them whatsoever.

It was then she started to do serious study on the physiology of not only the horse but of the plants they were consuming. She conducted multiple forage tests and compared this to what horses in the wild or on very rough grazing on big country farms (who show none of these symptoms) would eat and discovered some major discrepancies.

The penny was beginning to drop.

1. Horses in the wild eat serious roughage from a large variety of UNFERTILISED grasses, herbs and shrubs - compared to many of our horses who are confined behind fences and forced to eat rye and clover or short green fertilised grass.
2. The plants the horses eat in the wild often have deep tap roots which bring up many of the minerals required for the horse to be healthy - these plants are absent from the domestic horses pasture.
Of course everyone knew their horses tended to become extra 'hot' in spring and often in autumn (with laminitis and head flicking also more common in these seasons too)

But all year round 'Grass Affected' horses are very common. More so these days compared to 20-30 years ago. Real-estate is much more expensive now and many people keep their horses on small blocks and think that a paddock of grass is all they need. But as most of you are learning: not all grass is equal.
