The developmental phase is defined as the time between the initial exposure to the causative agent or incident, until the onset of clinical signs. It generally lasts 24–60 hours, and is the best time to treat a laminitis episode. Clinical laminitis may be prevented if cryotherapy (icing) is initiated during the developmental phase.

Chronic lameness will change the shape of the hoof capsule, since the lame limb is not weighted as much as its partner, making the capsule more upright, narrow, with a higher heel on the lame limb and more flattened on the sound one. [10] Hoof or horseshoe wear can indicate breakover and if the horse is dragging its toes. Change in shape of the ...
By July 13, Barbaro had developed a severe case of laminitis in the left hind hoof—a potentially life-threatening affliction that is common in horses who shift weight to one hoof for extended periods to keep pressure off an injured hoof. A procedure called a hoof wall resection removed 80% of his left rear hoof. The remaining 20% of his hoof ...
The contralateral (opposite) leg then bears all of the weight, which reduces blood flow to the hoof and strains the attachments of the laminae, leading to laminitis. Although support-limb laminitis is a risk for any horse that is not weight-bearing lame, occurring in roughly 16% of cases, it is uncommon in foals and yearlings. [ 135 ]
Early intervention is key; in one study, shoeing was successful in 97% of horses treated within ten months of the onset of signs, while only 54% of horses lame for over a year responded. [ 16 ] Advocates of barefoot trimming cite recent studies which show that removing the shoes can help alleviate the symptoms of navicular disease, and in some ...
Support limb laminitis, which is the specific type Barbaro had, is caused by over-stressing the good leg during recovery from an injury in the opposite limb. [15] [16] A 1986 survey done by the Morris Animal Foundation found that laminitis was the fourth leading cause of death among horses. [17]
Natural hoof supplements can be used as a boost to the immune systems of horses when concerned with laminitis or other hoof ailments. D-Biotin supplements, often including the sulfur-containing amino acid dl-Methionine, are commonly known supplements that may be helpful for managing hoof health if they're deficient/imbalanced in the diet.

A change of .5 inches (1.3 cm) in muscle attachment can affect range of motion by 3.5 inches (8.9 cm) and propulsion power by 20 percent. [24] "Form to function" is a term used in the equestrian world to mean that the "correct" form or structure of a horse is determined by the function for which it will be used.
