If you ask 100 people about Horses...You Will get 100 Different Answers....
A very old Virginian Horseman taught me a Very Valuable Lesson...
We are ALL made up of the same things...Flesh,Blood,Bone,Water...
If you Don't or Do it to Your Body,Then You Don't/Do it to a Horse...
It is all common sense
Do you file/cut your nails every 6 to 8 weeks???? You bet you do...
Nails/Hooves are made of Calcium...Connected to the body whose heart beats based on exercise(Increasing blood flow)...this stimulates Growth...so their Hooves need to betrimmed Every 6 to 8 weeks based on exercise...You will see the Growth...
How often do you get Your Teeth Cleaned???? 2x per year...answers the Floating question....Same principle, the more they use them,the type of food and pasture they are on determines the amount of filing they need....

No One Human Being can give you a Panacea for Colic....yes,It is Inflammation/Twisting of the Stomach/Intestine....Ever had indigestion????? You are a Human...You can Burp/Vomit....Look at their Skeleton...they cannot.....so the inflammation Must be handled differently....Plus they cannot communicate....so when they lay down and roll from a Gas bubble...they cause more damage...because you can't stand there and say...lay still and quiet,and it will go away with one good belch!!!!
Plus There are SO MANY types of colic...You cannot remedy them ALL by walking.....that is good for a gas bubble...but do you/the person Telling you to do this/ know how to tell if it gas?????
Find the Silent Pocket in their stomache.....

Many Variables...Go to Borders.com or amazon.com....look for ANY books by Suan B. Harris...She has written a few Great Books on care and feeding....
