The dog-fanged frog was a cryptid frog reported from the Belgian Congo, now the Democratic Republic of the Congo, once in 1945. According to the Administrator of the Niangara Territory, C. Caseleyr, an askari at Tapili was attacked by a very large frog, which he killed with a large club. When he told Caseleyr about the incident, with the frog's body as proof, it was discovered that the askari had "two puncture marks resembling the wounds that a dog's teeth would leave"; and indeed, the frog did have a set of sharp canine teeth in its upper and lower jaws, alongside a forked tongue. Other than these features, the frog was "large, broad, and fat," grey-green on its back, with a large orange patch on its chest and stomach.[1][2]


The African Bullfrog matches most characteristics of the dog-toothed frog quite well, and does not hesitate to bite humans and other threats. This young individual is slightly lighter in color than the massive adults.

The African Bullfrog (Pyxicephalus Adsperus) is the second largest frog in africa and one of the largest in the world. It generally agrees with the description given to Caseleyr. The back is a dull grey-green, and the stomach is white with patches of bright orange. In the mouth is a forked tongue and sharp canines used to kill prey. The bullfrog is known to be a voracious predator that does not shrink from aggressors many times larger than it. However, the african bullfrog is not officially recorded in the Congo. Caseleyr's specimen may represent an unknown but related species, a transient specimen of P. adsperus, or a member of an as-of-yet unacknowledged population.[3]
