The wild dogs in the forest share the environment with bears, their predators.
Some wild dogs in the environment don't have dark fur like the other wild dogs. The darker wild dogs blend in more with the forest ground. The wild dogs with the darker coat can sense if something or someone is approaching or around them.
The wild dogs sixth sense works best with the dogs with the darker fur since their predator, the bears, also has brown fur.
Majority of the wild dogs are able to survive in their environment because of their sixth sense and their fur color. The wild dogs with the light coat have a disadvantage because they don't have the sixth sense and a dark coat. However, the population is at a good number.
