All insulating covers and blankets trap heat by preventing the movement of body heat away from the individual. One way is to catch radiation (infrared heat) and the other is to prevent air from carrying away heat through circulation. Wool absorbs the radiated heat, and most is not re-radiated from the opposite (top) side. Additionally, the thicker material blocks air flow from reaching the person beneath, creating a warmer air layer between the bedding and the blanket. Using only cotton sheets allow more of this warmed air to "leak out" through the thinner fabric.

A blanket to keep warm
It helps you keep warm but not by giving you heat (thermal energy). You give the blanket heat and it helps keep your heat in. This is also true among other warm things you wear or use when you need to keep warm like coats,blankets,sweaters,etc...
A blanket keeps you warm by trapping and retaining your body heat, creating a layer of insulation that helps to maintain your body temperature.
A horse blanket...? :/♥

warmblooded animals keep warm by generating their own heat when they are in a cooler environment.
When they have colds or by what you say it might be sick so you can keep it warm.
