  • Miniature Poodle


A successful collaboration between breeders and researchers resulted in the identification of the gene mutation that causes a crippling dwarfism in Miniature Poodles. A test is now available to identify carriers of the disease.Although it is commonly referred to as 'dwarf' dogs in the USA, it involves much more than short stature - in addition to stunted growth, affected dogs often exhibit misshapen limbs, shortened and bent long bones, enlarged joints, extended hind limbs flattening of the rib cage.

Dwarfism-OC has a simple autosomal recessive mode of inheritance.
