A 20-month-old female Boxer dog presented significant increase on the bilateral volume of the maxillaries. The necropsy revealed that the kidneys were reduced in size, pale, with lobular aspect, and reduced cortical-medullar ratio. The maxillaries cutting surface revealed trabecular aspect of brown-reddish color. In addition, the lesions observed by microscopy (asynchronic differentiation of nephrons, persistent mesenchyme, and atypical tubular epithelium) allowed establishing the diagnosis of renal dysplasia with secondary fibrous osteodystrophy.
