Dogs have ear mobility that allows them to rapidly pinpoint the exact location of a sound. Eighteen or more muscles can tilt, rotate, raise, or lower a dog's ear. A dog can identify a sound's location much faster than a human can, as well as hear sounds at four times the distance. [41] Dogs can lose their hearing from age or an ear infection. [42]

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Conversely, we are normally in surroundings that are considerably cooler than the body's core temperature of 37 °C (98.6 °F) creating a gradient for thermal energy flow from the core to the surroundings. Therefore, the body must ensure it can also minimize the loss of heat to around 100 watts, if it is to maintain core temperature.
Miller died in 1960, and the first edition of The Anatomy of the Dog was published posthumously in 1964, [1] with George C. Christensen and Howard E. Evans as co-authors. [2] Evans and Christensen also co-authored the second edition, published in 1979, retitled as Miller's Anatomy of the Dog . [ 3 ]
One of the first indicators your dog is about to get aggressive is a full-body stiffening. It’s often paired with alert ears, tall stance, wide eyes and a closed mouth. 40.
Thermoreceptors of the skin sense the temperature of water. A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.
