significant asymmetry of the front feet is a potential cause for concern (Figure 4.3). This is

because one foot will contract at the heels and become smaller if the gait of the horse is
VetBooks.ir altered over a period of time with reduced weight bearing on the limb for any reason.

The foot is then lifted and thoroughly cleaned so that the solar (ground) surface can be
assessed. The fit of the shoes and any abnormal wear patterns can be seen. The conformation

of the sole is noted. This is usually slightly concave in the front feet and more obviously
concave in the back ones. A thin layer of horn may then be scraped from the sole to check for

bruises and punctures. Hoof testers are then applied at regular intervals from the heel on each
side to the toe to test for any regions of abnormal sensitivity (Figure 4.4). Horses with thin
soles are naturally sensitive so the response is usually compared with that of the opposite

limb. If the vet is concerned that there may be an abscess or an area of bruising under the
shoe, then it will be removed for closer inspection. Hoof testers are also applied to the frog

and across the heels. Another test for foot pain if white line lesions or nail bind is suspected
is to tap the shoe at regular intervals and over each nail with the hoof testers or a hammer.
