On average most horses are trimmed every 6 – 8 weeks. This of course will depend on the rate of growth, if your horse is shod or not, and the time of year (horses tend to grow faster in the summer). For the majority of horses 6 weeks is an appropriate time frame between trims. Keeping your horse on a continuous schedule will allow your farrier to stay on top of any corrections and abnormalities which can occur with growth. Feet which are allowed to become over grown can develop laminal stretching, laminal breakdown, crushing of the heels, development of flares, and imbalance. Preventing developmental hoof problems is easier than correcting them.
