All animals which have a spine, or backbone, are classified in the phylum Chordata. There are three subphylums in Chordata: the first two are invertebrates - Urochordata (tunicates e.g. marine filter feeders such as sea squirts), Cephalachordata (lancelets e.g. sessile burrowing marine animals), while the third is Vertebrata (vertebrates - all mammals, birds, fish, reptiles and amphibians).
Dogs are in the Chordata phylum, therefore Pit Bulls are in the Chordata phylum.
Birds belong to the phylum Chordata, specifically the subphylum Vertebrata. This means that birds are vertebrate animals with a backbone.
