 | | While the survival of wolves and canids in the wild depended in part on the density of their thick, double-layer coat in cold weather and the ability to shed and allow good air circulation through their coat in warmer times, these factors are almost moot as survival tactics in domestic dogs. |
 | | Similarly, wild canids needed to blend into their surrounding to hunt prey and elude predators, but coat types and colors are now more related to aesthetics than survival. |
 | | Along with their color, dogs' coats vary in length, type, texture and density, from the herding puli's long, dense, water-resistant double coat to the stiff, short, bristly fur of the Chinese shar-pei. |
