Just vary the parameters, like windowsize and threshold until you find one that looks good. Exactly what edges do you want? Just the outer outline, or all the lines in the foot?

In my dog filter, adjust the window width and Gaussian width in the lines
gaussian1 = fspecial('Gaussian', 21, 15);
gaussian2 = fspecial('Gaussian', 21, 20);
