History of the Mustang

The Mustang descends from horses brought to the Americas by Spanish explorers and settlers beginning in the 16th century. Escaped and released horses formed wild herds that spread across the western plains, mixing with later ranch and cavalry stock. Shaped by survival in rugged terrain, Mustangs became tough, sure-footed, and resourceful. Once numbering in the millions, their populations declined sharply, leading to protection under the 1971 Wild Free-Roaming Horses and Burros Act managed by the Bureau of Land Management.

Common health issues in the Mustang and how to help

Like all horse breeds, the Mustang can be more prone to a few specific health conditions. Knowing the early signs helps you act quickly — always consult a qualified vet for diagnosis and treatment.

Dental problems

What it is: Like all horses, Mustangs can develop sharp points or uneven wear that make chewing difficult.

How to help: Routine veterinary dental checks and floating keep them eating comfortably.

Hoof problems

What it is: Their tough feet still need regular care in a domestic setting to prevent cracks, imbalance, or lameness.

How to help: A farrier and vet can keep the hooves trimmed, balanced, and sound.

Internal parasites

What it is: Grazing horses can carry worms that cause weight loss or a poor coat.

How to help: A vet-guided deworming and fecal-testing program keeps parasites in check.

This is general information for owners, not veterinary advice. If you are worried about your horse's health, contact your vet.
