Where is a dewlap on a cow?
The pendulous skin under the neck of an ox, which laps or licks the dew in grazing, or a similar feature on any other animal.
How long do lice live on cattle?

Cattle with hair loss, an unthrifty appearance, and leaving hair on fences and other objects from rubbing may be a sign of lice infestation (Figure 1). However other factors can mimic lice infestations such as natural shedding, poor nutrition, mite infestations, mineral deficiency, photosensitivity, and other diseases.
Why do cows have dewlaps?
Dewlaps are loose flaps of skin that hang from the necks of some animals, notably certain lizards, birds, and hoofed mammals. According to the final hypothesis, dewlaps help animals dissipate excess body heat.

How big is the dewlap on a common eland?
Male common elands develop large dewlaps that can droop more than 40 cm (15.7 inches) beneath their necks. The results indicated that, unlike in birds and lizards, the dewlap in hoofed mammals does not appear to play a role in sexual selection.
Does the dewlap play a role in sexual selection?
The results indicated that, unlike in birds and lizards, the dewlap in hoofed mammals does not appear to play a role in sexual selection. And in eland antelopes, large dewlap size was associated with higher, rather than lower, incidence of claw marks, which suggests the structure incurs a predation cost rather than serves as a predator deterrent.
