The hump spine above the hip to the chest cavity indicates it is a wild animal, the round ears and mottled color give it away as African. If it has a black line down the center of the head it is assuredly an African or offshoot.
They are carnivorous hunters and do not scavenge carrion.
I saw one of these, or something similar crossing my yard in Plano, a suburb of Dallas pop.200,000+. I was out in the yard with my kids when this thing crossed the street and was crossing between my house and my neighbors. It stepped and stared at me and my kids.
My first thoughts was that it was a dingo and I knew they would bite without warning so I just stood and kept eye contact. It appeared to have a broken front paw and looked really pathetic.
My neighbor came out and the thing walked off. I told him to call animal control because there was a mangy coyote or dingo or something roaming around. They informed him it was a coyote and that they had a pet name for it and could never catch it.
I have seen coyotes, even ones roaming the suburbs, but never one that looked like this thing.
