In order to study the histology of the nephrons ofDogs.Samples were collected from middle of Iraq. The result revealed that thekidney of Dog hadthick capsule. The kidneysoccupied by long nephrons which excrete concentrated urine.The rest were short loop nephrons. Some renal corpuscles were present in the region of juxamedullary and midcortical cortex region The large amount of renal corpuscle in juxamedullary region regarded as the structural properties of the dog kidney, to void concentration urine .The proximal convoluted tubules had large lumen and high cuboidal epithelium cells with spherical nuclei.
