Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, mustelids, and pinnipeds (seals, walruses and sea lions). The center of diversification for the Caniformia is North America and northern Eurasia. Caniformia stands in contrast to the other suborder of Carnivora, the Feliformia ("cat-like" carnivorans), the center of diversification of which was in Africa and southern Asia.
Caniformia is a major group of meat-eating mammals that includes dogs, bears, raccoons, weasels, and seals, distinguished by their "dog-like" characteristics and originating primarily in North America and northern Eurasia. It matters because it represents one of the two main divisions of carnivorous mammals, contrasting with the "cat-like" Feliformia group that evolved separately in Africa and southern Asia.

==Description== Most members of this group have nonretractile claws (the fisher, marten, sea otter (forepaws only), red panda, and ringtail, and some foxes have retractile or semi-retractile claws) and tend to be plantigrade (with the exception of the Canidae). Other traits that separate the Caniformia from the Feliformia is that caniforms have longer jaws and more teeth, with less specialized carnassial teeth. They also tend more towards omnivory and opportunistic feeding, while the feliforms, other than the viverrids, are more specialized for eating meat. Caniforms have single-chambered or partially divided auditory bullae, composed of a single bone, while in feliforms, the auditory bullae are double-chambered, composed of two bones joined by a septum. In the Caniformia, the bulbourethral glands and vesicula seminalis are always absent. Relative to body size, the baculum is usually longer in the Caniformia than in the Feliformia.
