For acute problems remove the horse from ALL green, grass until he is back to normal, then gradually and carefully reintroduce grass again.
It is necessary to lower potassium intake by immediately removing from the horse’s diet:
- short, green, growing grass, legumes like clover and lucerne
- soy-based feeds and protein meals
- molassed feeds
All of the above add to your horse’s potassium load and make it harder for his system to keep vital minerals in balance.
He will still be ingesting plenty of potassium (more than his daily requirement) from his 24/7 hay
-
When the grass is part or all of your horse’s diet and it is green!
-
When the hay isn’t ideal, meaning it is too ‘rich’ and still causing issues.
- If you are renting grazing and don’t have control over grass intake.
It needs to be introduced as per the directions on the back label. Start with a very little bit and increase every few days up to an amount where you can see a difference.
The larger the horse the more this will be.
For most horses this would probably be at least 60gms per day, for bigger horses on problem grass this could be up to 80gms am & pm.
Introducing slowly is very important because depending on individual requirements (size of horse, what sort of grass they are on, what the weather is doing), your horse may need to consume quite large amounts at times.
This is why there is no set dose rate. The amount your horse needs will vary with the season and the weather – as a general rule of thumb, increase until your horse is back to normal. Thereafter you will likely need less over dry spells and more when it rains. Increase the dose when it starts to rain, rather than after the rain is finished and the horse is showing signs. Be pro-active.
The best results have been observed when it has been used in conjunction with GrazeEzy along with our other recommended diet adjustments.
While you are building up GrazeEzy, feed SOS high dose to overcome more serious issues. Once the horse is back to normal, gradually drop the amount. Keep some on hand for adding when necessary.

FAQ
All your questions, answered.


The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. For humans, this range is quite narrow at 21–28 °C, but for horses it’s much broader at 5–25 °C.
This difference means we should avoid rugging horses based on how cold we feel. Over-rugging can lead to serious health issues, including metabolic problems and thermoregulatory dysfunction.
Tips for Choosing a Winter Rug Weight
-
Clipped horses may need a heavier gram fill to stay comfortable.
-
Remember: horses warm themselves more easily than they cool down under a rug. If unsure, choose a lighter rug.
-
Check your horse regularly to make sure they are neither too hot nor too cold.
-
Consider your horse’s age and natural ability to stay warm.
-
As a general guide, rugging is usually appropriate when temperatures drop below 5–10 °C, but always adjust for your horse’s individual needs.
-
Always ensure rugs are waterproof. A wet rug is worse than no rug at all.
This is an indicative guide only. Always take into account factors such as wind chill, your horse’s age, weight, and condition.
