Take a look at this African Wild Dog, it s one of the most vicious dogs ever seen, just look at what

Among the canids, the African wild dog has the most specialized adaptations for coat color, food, and pursuing prey with its cursorial (running) abilities. It has an elegant skeleton, and losing the first digit on its forefeet shortens its stride and boosts its speed. This feature allows it to hunt prey over great distances across broad plains. Except for the spotted hyena, its teeth are normally carnassial-shaped, and its premolars are the largest relative to body size of any surviving carnivoran. With the loss or reduction of the post-carnassial molars, the talonid has evolved into a cutting blade for flesh-slicing on the lower carnassials (first lower molars).

The dhole and the bush dog are two other hypercarnivores that have developed this adaptability. Among mammals, the African wild dog has one of the most diverse coat colors. Individuals have different patterns and colors, showing that the underlying genes are diverse. These coat patterns may serve as a communication, concealment, or temperature regulation adaptation. According to a study published in 2019, the lycaon lineage split from Cuon and Canis 1.7 million years ago due to this set of adaptations, which happened at the same time as giant ungulates (its prey) diversified.

The oldest L. pictus fossil dates back to 200,000 years ago and was found in HaYonim Cave, Israel.[21][1] The evolution of the African wild dog is poorly understood due to the scarcity of fossil finds. Some authors consider the extinct Canis subgenus Xenocyon as ancestral to both the genus Lycaon and the genus Cuon,[22][23][24][25]: p149  which lived throughout Eurasia and Africa from the Early Pleistocene to the early Middle Pleistocene. Others propose that Xenocyon should be reclassified as Lycaon. The species Canis (Xenocyonfalconeri shared the African wild dog's absent first metacarpal (dewclaw), though its dentition was still relatively unspecialised.[1] This connection was rejected by one author because C. (X.) falconeri's missing metacarpal was a poor indication of phylogenetic closeness to the African wild dog and the dentition was too different to imply ancestry
