Mammals do not have any more heat receptors on their tongues than they do on the rest of their body's. Why would the body exclude the mouth from nerves in tame animals from wild animals? It would not. Burning your mouth hurts more than say burning your arm, because there are not as many layers of skin to protect your mouth like the rest of your body. Mucus membranes tend to be very open more sensitive and unprotected. Wild or tame makes no difference.
The eyes, nose, skin and tongue HAVE sensory receptors.

Well, all parts of the human body has receptors. Those receptors connect with nerves and sends electrical and chemical impulses to your brain. Receptors include: skin, tongue, ears, eyes, etc.
