ABSTRACT This report describes the clinical, radiological, pathological and genetic features of an inherited dwarfism in the English Pointer. Gross enlargement of the distal ulnar, radial and tibial growth plates occurred in the first 6 weeks of life and radiographic skeletal abnormalities were present at other sites. The enlargement was due to increase in width of the zone of hypertrophic cartilage, but the columns of chondrocytes were well ordered. By 12 weeks of age an unusual type of degeneration was present beneath the surface of articular cartilage; this developed to widespread, patchy erosion of joint surfaces by 32 weeks. The genetics are compatible with a homozygous recessive mode of inheritance.
