Coyotes are a little thicker skinned so they take about 8-9 hrs with a fan at 45 degrees. Ive turned them after 4 when put up in a heated shed
fox take almost no time a couple hrs
This is with a box fan on med blowing on them. Without the fan it can take much longer.
Basically when the skin feels dry to the touch, and is still pliable turn it. throw a little borax on the arm pits and ears and youll be fine.
