The domestic dog (Canis familiaris) possesses an ischial flag (https://www.facebook.com/awdri.com.au/photos/a.339435487132/10152520888147133/?type=3).

This feature, viz. a conspicuously pale, bilaterally symmetrical patch on the buttocks, is restricted to individuals - produced by perhaps more than 100 breeds as different as chihuahua and rottweiler - with the black-and-tan colouration.

This, in turn, implies that the real main ancestor of the domestic dog - which was not the wolf (Canis lupus) - also featured an ischial flag. This is because no extant wild species of Canis possesses this feature.
Given the above, it occurs to me that perhaps the domestic dog is the only member of the Carnivora on Earth that retains an ischial flag in the extant fauna.
Bold colouration on the buttocks is associated with prey animals, rather than predators.
More particularly, they are associated, among mammals, with certain ungulates such as gazelles.
