Pads
Cushion-like part of animal foot.
The tough, superficial cutis (outer layer of skin) of the pad is keratinized and hairless.
Under the cutis is the thick subcutis. The fatty (adipose) tissue of the subcutis provides a cushion to absorb shock during locomotion.

Subcutis
The layer of tissue directly underlying the dermis.
Not considered to constitute the true skin.
It consists primarily of connective (collagenous and elastic) tissue and fatty (adipose) tissue.
Sweat glands are located in the subcutis of pads of dogs and cats. Wolves do not have sweat glands on their feet.
