Step-by-step explanation:
Most horses' hooves are typically trimmed and shod every 4 to 6 weeks. Horse hoof care is critical for the overall health and well-being of the animal, considering that proper foot care and maintenance are essential to prevent lameness and other hoof-related problems.
The frequency of trimming and shoeing can vary based on the horse's conformation, hoof growth rate, activity level, and environmental conditions. Regular maintenance by a professional farrier can help ensure that horses remain comfortable and functional whether they are actively working, competing, or simply enjoying pasture time.
