I just finished reading an interesting article in the latest issue of the
Quebec Equestrian Federation's monthly magazine. It discusses a study that was
financed by the American Quarter Horse Association and done by Dr. Robert
Bowker from the Michigan State University's College of Veterinary Medicine.
What was interesting about it is that it suggests that the breakdown of the
navicular bone is only a manifestation of the problem, rather than being the
problem itself. Rather, the hoof as a whole as well as management practices
need to be examined. It goes on to say that shoeing and insufficient turnout
can be primary problems because the hoof is not able to function as it should
in its natural state...the frog not coming into contact with the ground enough
and inadequate circulation of blood (i.e. if the horse is standing around
alot). Instead of putting bar shoes on the horse, the suggestion is that shoes
be removed and the foot trimmed so that the frog is in contact with the
ground. The horse should be turned out on pastur e as well as receive
regular exercise (as much as it can under the circumstances, even if it is
just walking in hand). Dr. Bowker sees navicular disease as a people problem
and that it is often a result of the horse being a "stall potato".
I am not trying to say there is anything wrong with your management
practices Maryanne, but perhaps all of the stall rest your horse was forced
into because of injuries is part of the reason for the navicular spur. I'm no
vet here, just throwing out some information I came across....and waiting for
your thoughts... :)
