Deformities of the fetlock are much more critical as the rapid growth phase is much shorter in this area, therefore not allowing as much time for correction as in the carpus or tarsus. These deformities should be addressed by one month of age. It is always tragic to see a beautiful weanling whose confirmation was ignored until preparations get under way for sale. But then, it is just too late. Have your veterinarian evaluate your foals early.
Correct conformation goes a long way in preserving soundness in any discipline.
Another aspect of foal management that too often goes ignored is good hoof care. Some people overlook hoof care because foals are usually not forced to exercise. Foals which spend a lot of time outdoors will keep their hooves worn down to a certain extent. But all foals need to have their hooves trimmed regularly. Foals with abnormally shaped hooves or those with rotational or angular limb deformities require trimming every three to four weeks to correct their problems.
