To understand this, look at heat as the energy possessed by vibrating atoms. Also remember that heat flows from hotter to colder objects. When a greater surface area of a particular body is in contact with a cooler body, the vibrating atoms of the hot body can strike a larger amount of the atoms from the cold body, thus effectively transferring heat energy ...
Like all good physicists we'll start by assuming the animal is spherical. Actually the calculation I'm going to describe is basically the same whatever shape the animal is, but choosing a sphere means I can write down some simple formulae. If the radius of the spherical animal is $r$, then the total area of its skin is the surface area of the sphere: $$ A ...
According to Stefan-Boltzmann law ,the thermal power radiated per unit surface area from any body is same for that object at a given temperature, regardless of its shape So when surface area increase thermal radiation increases, and the body cools down faster
